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. + +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 + +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) 2014 Ricky Elrod + + 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., + 59 Temple Place, Suite 330, Boston, MA 02111-1307 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) year 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. diff --git a/Setup.hs b/Setup.hs new file mode 100644 --- /dev/null +++ b/Setup.hs @@ -0,0 +1,2 @@ +import Distribution.Simple +main = defaultMain diff --git a/bindings-codec2.cabal b/bindings-codec2.cabal new file mode 100644 --- /dev/null +++ b/bindings-codec2.cabal @@ -0,0 +1,29 @@ +name: bindings-codec2 +version: 0.1.0.0 +synopsis: Very low-level FFI bindings for Codec2 +description: Bindings for Codec2 generated by jwiegley's c2hsc/bindings-dsl +homepage: https://github.com/relrod/Codec2-hs +license: GPL-2 +license-file: LICENSE +author: Ricky Elrod +maintainer: ricky@elrod.me +copyright: (C) 2014 Ricky Elrod +category: Bindings, FFI, Codec +build-type: Simple +cabal-version: >= 1.10 + +source-repository head + type: git + location: git://github.com/relrod/bindings-codec2 + branch: master + +library + exposed-modules: + Bindings.Codec2 + default-extensions: ForeignFunctionInterface + build-depends: base >= 4 && < 5 + , bindings-DSL >= 1.0.16 && < 1.1 + extra-libraries: codec2 + hs-source-dirs: src + default-language: Haskell2010 + cc-options: -fPIC diff --git a/src/Bindings/Codec2.hsc b/src/Bindings/Codec2.hsc new file mode 100644 --- /dev/null +++ b/src/Bindings/Codec2.hsc @@ -0,0 +1,18 @@ +{-# OPTIONS_GHC -fno-warn-unused-imports #-} +#include +#include +module Bindings.Codec2 where +import Foreign.Ptr +#strict_import + +{- struct CODEC2; -} +#opaque_t struct CODEC2 +#ccall codec2_create , CInt -> IO (Ptr ) +#ccall codec2_destroy , Ptr -> IO () +#ccall codec2_encode , Ptr -> Ptr CUChar -> Ptr CShort -> IO () +#ccall codec2_decode , Ptr -> Ptr CShort -> Ptr CUChar -> IO () +#ccall codec2_samples_per_frame , Ptr -> IO CInt +#ccall codec2_bits_per_frame , Ptr -> IO CInt +#ccall codec2_set_lpc_post_filter , Ptr -> CInt -> CInt -> CFloat -> CFloat -> IO () +#ccall codec2_get_spare_bit_index , Ptr -> IO CInt +#ccall codec2_rebuild_spare_bit , Ptr -> Ptr CInt -> IO CInt
