GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License. We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a
copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2)
will operate properly with a modified version of the library, if
the user installs one, as long as the modified version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Lesser General Public
License as published by the Free Software Foundation; either
version 2 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
Lesser General Public License for more details.
You should have received a copy of the GNU Lesser General Public
License along with this library; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the

Installation Instructions
*************************
Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005 Free
Software Foundation, Inc.
This file is free documentation; the Free Software Foundation gives
unlimited permission to copy, distribute and modify it.
Basic Installation
==================
These are generic installation instructions.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. (Caching is
disabled by default to prevent problems with accidental use of stale
cache files.)
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You only need
`configure.ac' if you want to change it or regenerate `configure' using
a newer version of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes awhile. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that the
`configure' script does not know about. Run `./configure --help' for
details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
If you have to use a `make' that does not support the `VPATH'
variable, you have to compile the package for one architecture at a
time in the source code directory. After you have installed the
package for one architecture, use `make distclean' before reconfiguring
for another architecture.
Installation Names
==================
By default, `make install' will install the package's files in
`/usr/local/bin', `/usr/local/man', etc. You can specify an
installation prefix other than `/usr/local' by giving `configure' the
option `--prefix=PREFIX'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
give `configure' the option `--exec-prefix=PREFIX', the package will
use PREFIX as the prefix for installing programs and libraries.
Documentation and other data files will still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' cannot figure out automatically,
but needs to determine by the type of machine the package will run on.
Usually, assuming the package is built to be run on the _same_
architectures, `configure' can figure that out, but if it prints a
message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the `--target=TYPE' option to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share, you
can create a site shell script called `config.site' that gives default
values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script). Here is a another example:
/bin/bash ./configure CONFIG_SHELL=/bin/bash
Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
configuration-related scripts to be executed by `/bin/bash'.
`configure' Invocation
======================
`configure' recognizes the following options to control how it operates.
`--help'
`-h'
Print a summary of the options to `configure', and exit.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

bio2jack - NEWS
--------
9/12/2004 - Check out ChangeLog for news ;-)
10/26/2003 - Updated to the new jack api, fixed a bunch of bugs
Removed all blocking functions, blocking is BAD as it could potentially
hold off the callback function.
1/13/2003 - Continuing to refine the api by working on the xine plugin.
Fixed a few bugs in the code. Uploaded newer packages to
sourceforge.
12/31/2002 - Sourceforge project is setup.

Bio(blocked i/o) 2 jack.
A library for enabling easy porting of blocked io(OSS/ALSA) applications to
the jack sound server(http://jackit.sourceforge.net). This library allows the
person porting the code to simply replace the calls into OSS/ALSA with
calls into interface functions of this library. The library buffers a
small amount of audio data and takes care of the rest of the jack
implementation including the linked list of audio data buffers and the jack
callback.
Interface functions:
TODO: once these become stable copy and paste from the header file
Currently these drivers use the bio2jack library:

## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse

## dummy dependencies for each header file. Too bad gcc doesn't do

OSC-address-space.h
Matt Wright, 11/20/97
Version 2.0 5/28/98
C interface for registering the nodes in the OSC address space for an
application.
include OSC-timetag.h before this file
****************************** Introduction ******************************
The model is based on our original C++ design and consists of two kinds of
objects:
methods are the leaf nodes of the address space hierarchy. A complete OSC
address corresponds to a particular method, which has a corresponding
callback procedure that will be invoked to implement commands sent by an
OSC client.
containers are branch nodes of the address space hierarchy, and contain
methods and other containers. Each container has a single namespace;
it cannot contain a method and a subcontainer with the same name.
For example, let's examine the OSC message "/resonators/foo/decay 2.5". The
address of this message is "/resonators/foo/decay" and the message has a
single argument, 2.5. We'd say that the object corresponding to the prefix
"/resonators" is a container, and that it contains another container whose
address is "/resonators/foo". The "/resonators/foo" container has a method
"decay".
The memory model used by this module is pre-allocation of fixed-size objects
for containers, methods, and other internal objects. This preallocated
memory is dynamically managed internally by a custom high-performance memory
allocator. When the preallocated memory runs out, this module calls an
optional realtime memory allocator that you provide. If your memory allocator
gives this module more memory, it will add it to the pool of objects and
never free the memory. If your system does not have a realtime memory
allocator, provide a procedure that always returns 0.
*/
/*************************** Type Definitions ******************************/
/* Users of this module don't get to see what's inside these objects */
typedef struct OSCContainerStruct *OSCcontainer;
typedef struct OSCMethodStruct *OSCMethod;
/* This makes it easy to change the way we represent symbolic names: */
typedef const char *Name;
/************************ Initialization and Memory ************************/
/* You will fill an OSCAddressSpaceMemoryTuner struct with the parameters that
determine how memory will be allocated.
initNumContainers is the number of containers that will be allocated at
initialization time. This should be the maximum number of containers you
ever expect to have in your address space.
initNumMethods is the number of methods that will be allocated at
initialization time. If you register the same method callback procedure
multiple times at different places in the address space, each of these
locations counts as a separate method as far as memory allocation is
concerned.
The MemoryAllocator fields are procedures you will provide that allocate
memory. Like malloc(), they take the number of bytes as arguments and return
either a pointer to the new memory or 0 for failure. This memory will never
be freed.
The InitTimeMemoryAllocator will be called only at initialization time,
i.e., before OSCInitAddressSpace() returns. If it ever returns 0, that's
a fatal error.
The RealTimeMemoryAllocator will be called if, while the application is
running, the address space grows larger than can fit in what was allocated
at initialization time. If the RealTimeMemoryAllocator() returns 0, the
operation attempting to grow the address space will fail. If your system
does not have real-time memory allocation, RealTimeMemoryAllocator should
be a procedure that always returns 0.

/**************************** Containers ****************************/
/* Here's how this system deals with the standard OSC queries addressed to
containers. This module handles the details of listening for these queries
and returning a correctly-formatted answer; all it needs from you is the
actual data that constitute the answers to these queries.
You pass this data in an OSCContainerQueryResponseInfo structure. Future versions
of this module may have new kinds of queries that they can deal with, so
the list of fields in this structure may grow. That's why your code should
call OSCInitContainerQueryResponseInfo() on your struct before putting new values
into it; this procedure will initialize all of the fields to 0, meaning
"don't have that information", which will cause the associated queries to
fail.
The "null" message, i.e., a message with a trailing slash, requesting the
list of addresses under a given container, is handled automatically.

This procedure doesn't make a copy of the name string or any of the

of the OSCContainerQueryResponseInfoStruct.

*/

/* A methodCallback is a procedure that you write that will be called at the
time that an OSC message is to take effect. It will be called with 5
arguments:
- A context pointer that was registered with the methodNode
this is a method of. (Something like the C++ "this" pointer.)
- The number of bytes of argument data
- A pointer to the argument portion of the OSC message
- The time tag at which this message is supposed to take effect.
- A "return address" object you can use to send a message back to the
client that sent this message. This return channel is guaranteed
to be usable only during the invocation of your method, so your method
must use the return address immediately or ignore it, not store it away
for later use.

value in the given buffer in the same format as the associated
methodCallback would expect its "args" argument, and should return the
length of data just like the method would expect in its "arglen" argument.

- Then each subsequent call to OSCQueueScanNext() returns a pointer to an
OSCSchedulableObject that is stored on the queue, until
OSCQueueScanNext() returns 0 to indicate that all objects on the queue
have been scanned.
The objects returned by OSCQueueScanNext() come in chronological order (or
approximately chronological order, depending on the underlying queue data
structure).
If you call OSCQueueRemoveCurrentScanItem(), the object most recently
returned by OSCQueueScanNext() will be removed from the queue.
If there are any insertions or deletions to the queue, the sequence of
scanned objects must still include every object in the queue. This may
cause a particular object to be returned more than once by
OSCQueueScanNext().

/**************************************************
Initialization and memory pre-allocation
**************************************************/
/* The memory model used by this module is pre-allocation of fixed-size
objects for network buffers and other internal objects. This preallocated
memory is dynamically managed internally by a custom high-performance memory
allocator. When the preallocated memory runs out, this module calls an
optional realtime memory allocator that you provide. If your memory
allocator gives this module more memory, it will add it to the pool of
objects and never free the memory. If your system does not have a realtime
memory allocator, provide a procedure that always returns 0.
You will fill an OSCReceiveMemoryTuner struct with the parameters that
determine how memory will be allocated.
The MemoryAllocator fields are procedures you will provide that allocate
memory. Like malloc(), they take the number of bytes as arguments and return
either a pointer to the new memory or 0 for failure. This memory will never
be freed.
- The InitTimeMemoryAllocator will be called only at initialization time,
i.e., before OSCInitAddressSpace() returns. If it ever returns 0, that's
a fatal error.
- The RealTimeMemoryAllocator will be called if, while the application is
running, the address space grows larger than can fit in what was allocated
at initialization time. If the RealTimeMemoryAllocator() returns 0, the
operation attempting to grow the address space will fail. If your system
does not have real-time memory allocation, RealTimeMemoryAllocator should
be a procedure that always returns 0.
The remaining fields say how much memory to allocate at initialization time:
- receiveBufferSize is the maximum packet size that can be received. Is the
maximum UDP packet size 4096? OSC clients can send a query to this system
asking for this maximum packet size.
- numReceiveBuffers determines how many packets at a time can be sitting
on the scheduler with messages waiting to take effect. If all the
receive buffers are tied up like this, you won't be able to receive
new packets.
- numQueuedObjects is the number of messages and packets that can be sitting
on the scheduler waiting to take effect.
- Because a message pattern may be dispatched before the message takes effect,
we need memory to store the callback pointers corresponding to a message.
numCallbackListNodes is the number of callbacks that may be stored in this
fashion. It must be at least as large as the maximum number of methods that
any one message pattern may match, but if you want to take advantage of
pre-dispatching, this should be large enough to hold all the callbacks for
all the messages waiting in the scheduler.

Cache frames from file to memory
*/
/** \defgroup elcache Efficient Frame Caching
*
* Veejay stores each retrieved frame (from the EDL) in a temporary cache.
* The cache has at most N slots, in each slot an image buffer is placed
* together with a minimum of bookkeeping (frame number and decoder ID)
*
* The caching mechanism will trash when loading a new series of frames.
* As unknown frames are loaded, old frames will be discarded.
* A very long sample will thus beat the caching mechanism if the sample only
* loops forward.
*
* This cache does *not* read-ahead, instead it keeps already played frames for repated usage.
* The caching mechanism is intended for sample playback usage. It is
* only used when looping samples that typically access compressed image data repeatedly.
* The price for such a situation is the time needed to memory-to-memory copy the image buffer.
*
* Veejay estimates the number of slots it can claim by taking a percentage
* of the available system memory.
* The caching mechanism is disabled by default.

* the single member int __OPAQUE__. This way, any attempts by the
* client code to violate the principles of information hiding (by accessing
* the structure directly) can be diagnosed at translation time. However,
* note the resulting compiled unit is not suitable for linking.
* 2. This is a pointer to the next node in the chain. In the last node of a
* chain, this pointer is null.
* 3. The key is a pointer to some user supplied data that contains a unique
* identifier for each hash node in a given table. The interpretation of
* the data is up to the user. When creating or initializing a hash table,
* the user must supply a pointer to a function for comparing two keys,
* and a pointer to a function for hashing a key into a numeric value.
* 4. The value is a user-supplied pointer to void which may refer to
* any data object. It is not interpreted in any way by the hashing
* module.
* 5. The hashed key is stored in each node so that we don't have to rehash
* each key when the table must grow or shrink.

* This is the hash table control structure. It keeps track of information
* about a hash table, as well as the hash table itself.
* Notes:
* 1. Pointer to the hash table proper. The table is an array of pointers to
* hash nodes (of type hnode_t). If the table is empty, every element of
* this table is a null pointer. A non-null entry points to the first
* element of a chain of nodes.
* 2. This member keeps track of the size of the hash table---that is, the
* number of chain pointers.
* 3. The count member maintains the number of elements that are presently
* in the hash table.
* 4. The maximum count is the greatest number of nodes that can populate this
* table. If the table contains this many nodes, no more can be inserted,
* and the hash_isfull() function returns true.
* 5. The high mark is a population threshold, measured as a number of nodes,
* which, if exceeded, will trigger a table expansion. Only dynamic hash
* tables are subject to this expansion.
* 6. The low mark is a minimum population threshold, measured as a number of
* nodes. If the table population drops below this value, a table shrinkage
* will occur. Only dynamic tables are subject to this reduction. No table
* will shrink beneath a certain absolute minimum number of nodes.
* 7. This is the a pointer to the hash table's comparison function. The
* function is set once at initialization or creation time.
* 8. Pointer to the table's hashing function, set once at creation or
* initialization time.
* 9. The current hash table mask. If the size of the hash table is 2^N,
* this value has its low N bits set to 1, and the others clear. It is used
* to select bits from the result of the hashing function to compute an
* index into the table.
* 10. A flag which indicates whether the table is to be dynamically resized. It
* is set to 1 in dynamically allocated tables, 0 in tables that are
* statically allocated.

/** @mainpage frei0r - a minimalistic plugin API for video effects
*
* @section sec_intro Introduction
*
* This is frei0r - a minimalistic plugin API for video effects.
*
* The main emphasis is on simplicity - there are many different applications
* that use video effects, and they all have different requirements regarding
* their internal plugin API. And that's why frei0r does not try to be a
* one-in-all general video plugin API, but instead an API for the most
* common video effects: simple filters, sources and mixers that can be
* controlled by parameters.
*
* It's our hope that this way these simple effects can be shared between
* many applications, avoiding their reimplementation by different
* projects.
*
* On the other hand, this is not meant as a competing standard to
* more ambitious efforts that try to satisfy the needs of many different
* applications and more complex effects.
*
*
* @section sec_overview Overview
*
* If you are new to frei0r, the best thing is probably to have
* a look at the <a href="frei0r_8h-source.html">frei0r header</a>,
* which is quite simple.
*
* After that, you might want to look at the
* <a href="frei0r_8h.html">frei0r functions</a> in more detail.
*
* When developing a new frei0r effect, you have to choose
* - which effect type to use (\ref PLUGIN_TYPE),
* - which color model to use (\ref COLOR_MODEL), and
* - which parameter types (\ref PARAM_TYPE) your effect will support.
*
* To round things up, you should decide whether your effect should have
* an associated icon (\ref icons), and where it will be installed
* (\ref pluglocations).
*
* @section sec_changes Changes
*
* @subsection sec_changes_1_0_1_1 From frei0r 1.0 to frei0r 1.1
*
* - added specifications for plugin locations
* - added specifications for frei0r icons
* - added RGBA8888 color model
* - added packed32 color model
* - added better specification of color models
* - added string type
* - added bounds to resolution (8 <= width, height <= 2048)
* - width and height must be an integer multiple of 8
* - frame data must be 16 byte aligned
* - improved update specification (must not change parameters,
* must restore fpu state)
* - added note for applications to ignore effects with unknown fields
* - added new plugin types mixer2 and mixer3
* - added section about \ref concurrency
*/
/**
* \addtogroup pluglocations Plugin Locations
* @section sec_pluglocations Plugin Locations
*
* For Unix platforms there are rules for the location of frei0r plugins.
*
* frei0r 1.x plugin files should be located in
*
* - (1) /usr/lib/frei0r-1/\<vendor\>
* - (2) /usr/local/lib/frei0r-1/\<vendor\>
* - (3) $HOME/.frei0r-1/lib/\<vendor\>
*
* Examples:
*
* - /usr/lib/frei0r-1/mob/flippo.so
* - /usr/lib/frei0r-1/drone/flippo.so
* - /usr/local/lib/frei0r-1/gephex/coma/invert0r.so
* - /home/martin/.frei0r-1/lib/martin/test.so
*
* Like in these examples plugins should be placed in "vendor" subdirs
* to reduce name clashes.
*
* @subsection sec_order Plugin Loading Order
*
* The application shall load plugins in the following order: 3, 2, 1.
* If a name clash occurs (two or more frei0r plugins with identical
* effect name), the plugins in directory 3 have precedence over plugins
* in directory 2, and those in directory 2 have precedence over plugins
* in directory 1.
*
* This makes it possible for users to "override" effects that are
* installed in system wide directories by placing plugins in their
* home directory.
*
* The order of loading plugins inside each of the directories
* 1, 2, and 3 is not defined.
*/
/**
*\addtogroup icons Icons for frei0r effects
* @section sec_icons Icons for frei0r effects
*
* Each frei0r effect can have an associated icon.
*
* @subsection sec_icon_format Icon Format
*
* The format of frei0r icons must be png.
* Recommended resolution is 64x64.
* The icon filename of an effect with effect name "frei0r"
* must be "frei0r.png".
*
* @subsection sec_icon_location Icon location
*
* The exact location where the application should look for the
* plugin is platform dependant.
*
* For Windows platforms, the icon should be at the same place as
* the plugin containing the effect.
*
* For Unix platforms, the following mapping from plugin location
* to icon location must be used:
*
* Let \<plugin_path\>/\<plugin\> be a frei0r plugin with name \<effect_name\>.
* Then the corresponding icon (if any) shall be located in
* \<icon_path\>/\<effect_name\>.png.
* \<icon_path\> can be obtained in the following way:
*
* @verbatim
<plugin_path> | <icon_path>
----------------------------------------------------------------------------
$HOME/.frei0r-1/lib/<vendor> | $HOME/.frei0r-1/icons/<vendor>
/usr/local/lib/frei0r-1/<vendor> | /usr/local/share/frei0r-1/icons/<vendor>
/usr/lib/frei0r-1/<vendor> | /usr/share/frei0r-1/icons/<vendor>
* | <plugin_path>
@endverbatim
*
* (The wildcard '*' stands for any other plugin_path)
*
* For other platforms, no location is defined. We recommend to use the
* plugin path where possible.
*/
/**
* \addtogroup concurrency Concurrency
* @section sec_concurrency Concurrency
*
* - \ref f0r_init

/** \addtogroup COLOR_MODEL Color Models
* List of supported color models.
*
* Note: the color models are endian independent, because the
* color components are defined by their positon in memory, not
* by their significance in an uint32_t value.
*
* For effects that work on the color components,
* RGBA8888 is the recommended color model for frei0r-1.1 effects.
* For effects that only work on pixels, PACKED32 is the recommended
* color model since it helps the application to avoid unnecessary
* color conversions.
*
* Effects can choose an appropriate color model, applications must support
* all color models and do conversions if necessary. Source effects
* must not use the PACKED32 color model because the application must know
* in which color model the created framebuffers are represented.
*
* For each color model, a frame consists of width*height pixels which
* are stored row-wise and consecutively in memory. The size of a pixel is
* 4 bytes. There is no extra pitch parameter
* (i.e. the pitch is simply width*4).
*
* The following additional constraints must be honored:
* - The top-most line of a frame is stored first in memory.
* - A frame must be aligned to a 16 byte border in memory.
* - The width and height of a frame must be positive
* - The width and height of a frame must be integer multiples of 8
*
* These constraints make sure that each line is stored at an address aligned
* to 16 byte.
