GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 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.
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.
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.

"Duke Nukem 3D" copyright 1996 - 2003 3D Realms. All trademarks and copyrights reserved.
This is the complete source code for Duke Nukem 3D version 1.5, buildable as detailed in the next section.
The code is licensed under the terms of the GPL (gnu public license). You should read the entire license (filename "GNU.TXT" in this archive), so you understand your rights and what you can and cannot do with the source code from this release.
All of the Duke Nukem 3D data files remain copyrighted and licensed by 3D Realms under the original terms. You cannot redistribute our data or data files from the original game. You can use our data for personal entertainment or educational purposes. If you need the data, you can order a Duke Nukem 3D CD from our store on our website.
Please do not contact us for possible commercial exploitation of Duke Nukem 3D -- we will not be interested.
Please note that this is being released without any kind of support from Apogee Software, Ltd / 3D Realms Entertainment. We cannot help in getting this running and we do not guarantee that you will be able to get it to work, nor do we guarantee that it won't blow up your computer if you do try and use it. Use at your own risk.
SPECIAL THANKS
--------------
First, we'd like to thank all the fans of 3D Realms and Duke Nukem. We wouldn't be where we are without you and without your support.
Second, we'd like to thank Charlie Wiederhold for putting this release together. We had decided some time ago to release the source code, but people are busy and it always seemed to be low priority. A couple of weeks ago, Charlie got a source archive from Scott, and came back a few days later with it all compiling.
Thanks also to Ken Silverman and Jim Dose for allowing us to include some of their source in this build, so we have it all in one archive.
Finally, we'd like to thank the whole Duke Nukem Forever team. These guys are all working incredibly hard on the next installment of Duke Nukem.
Enjoy the source code. We can't wait to see what people do with it. And we really look forward to being able to play the game under XP, with sound, internet play, hardware acceleration and whatever else you're clever enough to put in :)

======================================================
HOW TO COMPILE THE SOURCE CODE (by Charlie Wiederhold)
======================================================
This source code release was compiled on March 20th, 2003 using the materials in this archive.
Duke was originally written with the Watcom 10.0 C/C++ compiler. This code has been updated to allow it to compile under the free version of the Watcom compiler available from their webpage (http://www.openwatcom.org).
It was compiled under both Open Watcom 1.0 and Watcom 11.0c for Windows. Both are free to download, and I didn't notice much of a difference between the two when using them. This means, thankfully, that anybody can work with this code right away without trying to find an out of production compiler or wait for someone to port it to other modern compilers.
Step 1) Install Watcom C/C++ onto your system.
Step 2) When you install, make sure that you select DOS 32 Bit as one of your target environments to build for.
Step 3) Choose a place you want to work from and unzip the contents of this .ZIP file into that directory.
From here you have two choices on how to work. You can use the command line compiler that comes with Watcom, or you can use the IDE (basically the development studio that manages your files, options for compiling, editing files, debugger, etc). Whichever one you choose depends on what you are comfortable with.
IF YOU USE THE COMMAND LINE COMPILER
------------------------------------
- In a Command Prompt, go into the Source directory where you should find a MAKEFILE. and a MAKEFILE.LNK file.
- At the Command Prompt type "wmake" or "wmake makefile" without the quotes.
- This should compile and create a DUKE3D.EXE file which you can then copy into the directory with your Duke 3D data and run.
IF YOU USE THE IDE
------------------
- Start up the Watcom IDE and go to File -> Open Project.
- Find the directory where you've unzipped the Source files into, and you should see a DUKE3D.WPJ, select this and hit "OK".
- Click the "Make Current Target" button, or press "F4" or go to the menu Targets -> Make. You'll see lots of Warnings as it compiles, that's normal.
- This will create a DUKE3D.EXE file in the same directory where the DUKE3D.WPJ was located, which can then be copied in the directory with your Duke 3D data and run.
ONCE YOU HAVE DUKE3D.EXE COMPILED
---------------------------------
- If you own Duke 3D version 1.5, you are set... simply copy your new .EXE into the directory and run it.
- If you own Duke 3D version 1.4 or 1.3d, follow the same steps below except don't download the shareware data.
- If you own neither versions: Download the shareware version of Duke 3D from http://www.3drealms.com (go to Downloads).
- In the directory you have Duke 3D installed now, copy the four files in the TESTDATA directory into your Duke 3D directory. Now you should be able to play the game well enough to test, though unfortunately there will still be some minor issues. Your best results will come from owning a copy of Duke 3D version 1.5, which can still be purchased from the 3D Realms website.
This should be enough to get you started. Unfortunately nobody at 3D Realms will be able to devote the time to answer any support questions if you do encounter problems. However, go to http://www.3drealms.com/forums.html and you will find people discussing the source code in the Duke 3D Source category and able to answer questions. I will try to answer extremely common questions there shortly after the release, but I promise, within a very short time the community will outgrow my knowledge/understanding of this source and be better suited to answer any questions itself.
MISC NOTES ABOUT THIS RELEASE
-----------------------------
- All changes I made from the original are indicated by a "// CTW" style comment. In all but one case I commented out the original code so that it would still be there. I made as few changes as possible since the fun for people is working on the Duke 3D original code, not my personal rewrite/interpretation.
- Unfortunately the source to the SETUP.EXE and SETMAIN.EXE programs used for creating setup configuration files for Duke 3D is nowhere to be found, so if you need a setup utility to create custom .CFG files you'll need to write your own. If we find the source code we'll update this release to include that as well. The code to read .CFG files is within the Duke 3D CONFIG.C source itself, so it gives you something to start with.
- This source includes the Build Engine data (.OBJ files) needed for compiling. The Build Engine is a seperate entity from Duke 3D, though Duke 3D is built upon the Build Engine.
- The BUILDENGINE.ZIP file contains all of the data you need from Ken Silverman's released version to compile the Build Engine itself. Instructions for doing this are contained within that file. I have tested this with the free versions of Watcom and it works. More information about this code at Ken's webpage here: http://www.advsys.net/ken/buildsrc/default.htm
- The AUDIOLIB.ZIP file contains all of the data you need from Jim Dose's sound engine that was used in both Rise of the Triad and Duke 3D to compile the actual Audio Library itself. Instructions for doing this are contained in that file. I have not tested this personally to see if it compiles under the free version of Watcom.
- Sound will be sketchy if you are on any modern system. It does work, but only as well as the original Duke 3D's does.
- Networking works. Scott Miller and I fired up a quick game and it worked fine. The only catch is you need to disable sound for this to work in modern systems. No testing over a modem was done.
- The original .DMO demo files do not work. However recording new ones and playing those back does work, sometimes. I've disabled playback of demos in the source for stability when people first try to run their compiled version. It shouldn't be too hard to find how to re-enable it for those who want to go in and fix it.
- If you would like to play Duke 3D in high res Vesa modes instead of 320x200, download Ken's utility here: http://www.advsys.net/ken/build.htm
- The files in the EXTRAS folder are there purely for curiosity and educational purposes. Things like Allen Blum's experiments with room over room can be found in there, as well as older versions of the source files that ultimately made it into the game. None of these are necessary and are purely, well, extra.
- Duke 3D used DOS/4GW for it's DOS Extender. Watcom 1.0/11.0c comes with a couple free DOS Extenders, however you will need to bind it to the extender in order to distribute the EXE you create to other computers where it wasn't compiled. How you do this depends on which extender you choose to use. I trust that once you get to the point of distributing an EXE you can figure out how to bind it to the extender. Since DOS/4GW was a commercial licensed product, we can't distribute the resources we used to do this.
- All references to TEN (Total Entertainment Network) have been commented out of the version that will be compiled, but left in for the curious to look at.
- This page was an invaluable learning tool for me when working on preparing the source code for release: http://www.clipx.net/ ... The actual information I used can be found here: http://www.clipx.net/ng/zcpp/index.php
- I started working on this having no knowledge of Watcom, DOS based C programming, etc. and got it up and going within a night (and a half...ish) after work hours. So if you have a basic understanding of programming, you shouldn't have much trouble getting this up and running.
- The first things I think everyone would like to see done is an update to the sound engine and an update to the networking to allow play over the internet. But there is no end to the changes people can make, so everyone at 3D Realms looks forward to what people will do now that the source code is finally out there. It's been a long time coming (too long probably), but here you go, have fun!

Addendum submitted by Votis Kokavessis:
After some experimenting with .VOC files I found out that there is a Data Block Type 9, which is not covered in the VOC.TXT file. Here is what I was able to discover about this block type:
TYPE: 09
SIZE: 12 + length of data
INFO: 12 (twelve) bytes
INFO STRUCTURE:
Bytes 0-1: (Word) Sample Rate (e.g. 44100)
Bytes 2-3: zero (could be that bytes 0-3 are a DWord for Sample Rate)
Byte 4: Sample Size in bits (e.g. 16)
Byte 5: Number of channels (e.g. 1 for mono, 2 for stereo)
Byte 6: Unknown (equal to 4 in all files I examined)
Bytes 7-11: zero
----------------------------------------------------------------------------------
Detailed description of new data blocks (VOC files version 1.20 and above):
(Source is fax from Barry Boone at Creative Labs, 405/742-6622)
BLOCK 8 - digitized sound attribute extension, must preceed block 1.
Used to define stereo, 8 bit audio
BYTE bBlockID; // = 8
BYTE nBlockLen[3]; // 3 byte length
WORD wTimeConstant; // time constant = same as block 1
BYTE bPackMethod; // same as in block 1
BYTE bVoiceMode; // 0-mono, 1-stereo
Data is stored left, right
BLOCK 9 - data block that supersedes blocks 1 and 8.
Used for stereo, 16 bit.

// have a size of 16 bytes
Valid values of wFormat are:
0x0000 8-bit unsigned PCM
0x0001 Creative 8-bit to 4-bit ADPCM
0x0002 Creative 8-bit to 3-bit ADPCM
0x0003 Creative 8-bit to 2-bit ADPCM

* This module describes the three decoder layers provided by libFLAC++.
*
* The libFLAC++ decoder classes are object wrappers around their
* counterparts in libFLAC. All three decoding layers available in
* libFLAC are also provided here. The interface is very similar;
* make sure to read the \link flac_decoder libFLAC decoder module \endlink.
*
* The only real difference here is that instead of passing in C function
* pointers for callbacks, you inherit from the decoder class and provide
* implementations for the callbacks in the derived class; because of this
* there is no need for a 'client_data' property.

*
* \brief
* This module contains structure definitions for the representation
* of FLAC format components in memory. These are the basic
* structures used by the rest of the interfaces.
*
* First, you should be familiar with the
* <A HREF="../format.html">FLAC format</A>. Many of the values here
* follow directly from the specification. As a user of libFLAC, the
* interesting parts really are the structures that describe the frame
* header and metadata blocks.
*
* The format structures here are very primitive, designed to store
* information in an efficient way. Reading information from the
* structures is easy but creating or modifying them directly is
* more complex. For the most part, as a user of a library, editing
* is not necessary; however, for metadata blocks it is, so there are
* convenience functions provided in the \link flac_metadata metadata
* module \endlink to simplify the manipulation of metadata blocks.
*
* \note
* It's not the best convention, but symbols ending in _LEN are in bits
* and _LENGTH are in bytes. _LENGTH symbols are \#defines instead of
* global variables because they are usually used when declaring byte
* arrays and some compilers require compile-time knowledge of array
* sizes when declared on the stack.
*

* \brief
* This module describes the three decoder layers provided by libFLAC.
*
* For decoding FLAC streams, libFLAC provides three layers of access. The
* lowest layer is non-seekable stream-level decoding, the next is seekable
* stream-level decoding, and the highest layer is file-level decoding. The
* interfaces are described in the \link flac_stream_decoder stream decoder
* \endlink, \link flac_seekable_stream_decoder seekable stream decoder
* \endlink, and \link flac_file_decoder file decoder \endlink modules
* respectively. Typically you will choose the highest layer that your input
* source will support.
*
* The stream decoder relies on callbacks for all input and output and has no
* provisions for seeking. The seekable stream decoder wraps the stream
* decoder and exposes functions for seeking. However, you must provide
* extra callbacks for seek-related operations on your stream, like seek and
* tell. The file decoder wraps the seekable stream decoder and supplies
* most of the callbacks internally, simplifying the processing of standard
* files.
*/
/** \defgroup flac_stream_decoder FLAC/stream_decoder.h: stream decoder interface
* \ingroup flac_decoder
*
* \brief
* This module contains the functions which implement the stream
* decoder.
*
* The basic usage of this decoder is as follows:
* - The program creates an instance of a decoder using
* FLAC__stream_decoder_new().
* - The program overrides the default settings and sets callbacks for
* reading, writing, error reporting, and metadata reporting using
* FLAC__stream_decoder_set_*() functions.
* - The program initializes the instance to validate the settings and
* prepare for decoding using FLAC__stream_decoder_init().
* - The program calls the FLAC__stream_decoder_process_*() functions
* to decode data, which subsequently calls the callbacks.
* - The program finishes the decoding with FLAC__stream_decoder_finish(),
* which flushes the input and output and resets the decoder to the
* uninitialized state.
* - The instance may be used again or deleted with
* FLAC__stream_decoder_delete().
*
* In more detail, the program will create a new instance by calling
* FLAC__stream_decoder_new(), then call FLAC__stream_decoder_set_*()
* functions to set the callbacks and client data, and call
* FLAC__stream_decoder_init(). The required callbacks are:
*
* - Read callback - This function will be called when the decoder needs
* more input data. The address of the buffer to be filled is supplied,
* along with the number of bytes the buffer can hold. The callback may
* choose to supply less data and modify the byte count but must be careful
* not to overflow the buffer. The callback then returns a status code
* chosen from FLAC__StreamDecoderReadStatus.
* - Write callback - This function will be called when the decoder has
* decoded a single frame of data. The decoder will pass the frame
* metadata as well as an array of pointers (one for each channel)
* pointing to the decoded audio.
* - Metadata callback - This function will be called when the decoder has
* decoded a metadata block. In a valid FLAC file there will always be
* one STREAMINFO block, followed by zero or more other metadata
* blocks. These will be supplied by the decoder in the same order as
* they appear in the stream and always before the first audio frame
* (i.e. write callback). The metadata block that is passed in must not
* be modified, and it doesn't live beyond the callback, so you should
* make a copy of it with FLAC__metadata_object_clone() if you will need
* it elsewhere. Since metadata blocks can potentially be large, by
* default the decoder only calls the metadata callback for the STREAMINFO
* block; you can instruct the decoder to pass or filter other blocks with
* FLAC__stream_decoder_set_metadata_*() calls.
* - Error callback - This function will be called whenever an error occurs
* during decoding.
*
* Once the decoder is initialized, your program will call one of several
* functions to start the decoding process:
*
* - FLAC__stream_decoder_process_single() - Tells the decoder to process at
* most one metadata block or audio frame and return, calling either the
* metadata callback or write callback, respectively, once. If the decoder
* loses sync it will return with only the error callback being called.
* - FLAC__stream_decoder_process_until_end_of_metadata() - Tells the decoder
* to process the stream from the current location and stop upon reaching
* the first audio frame. The user will get one metadata, write, or error
* callback per metadata block, audio frame, or sync error, respectively.
* - FLAC__stream_decoder_process_until_end_of_stream() - Tells the decoder
* to process the stream from the current location until the read callback
* returns FLAC__STREAM_DECODER_READ_STATUS_END_OF_STREAM or
* FLAC__STREAM_DECODER_READ_STATUS_ABORT. The user will get one metadata,
* write, or error callback per metadata block, audio frame, or sync error,
* respectively.
*
* When the decoder has finished decoding (normally or through an abort),
* the instance is finished by calling FLAC__stream_decoder_finish(), which
* ensures the decoder is in the correct state and frees memory. Then the
* instance may be deleted with FLAC__stream_decoder_delete() or initialized
* again to decode another stream.
*
* Note that the stream decoder has no real concept of stream position, it
* just converts data. To seek within a stream the callbacks have only to
* flush the decoder using FLAC__stream_decoder_flush() and start feeding
* data from the new position through the read callback. The seekable
* stream decoder does just this.
*
* The FLAC__stream_decoder_set_metadata_*() functions deserve special
* attention. By default, the decoder only calls the metadata_callback for
* the STREAMINFO block. These functions allow you to tell the decoder
* explicitly which blocks to parse and return via the metadata_callback
* and/or which to skip. Use a FLAC__stream_decoder_set_metadata_respond_all(),
* FLAC__stream_decoder_set_metadata_ignore() ... or FLAC__stream_decoder_set_metadata_ignore_all(),
* FLAC__stream_decoder_set_metadata_respond() ... sequence to exactly specify which
* blocks to return. Remember that some metadata blocks can be big so
* filtering out the ones you don't use can reduce the memory requirements
* of the decoder. Also note the special forms
* FLAC__stream_decoder_set_metadata_respond_application(id) and
* FLAC__stream_decoder_set_metadata_ignore_application(id) for filtering APPLICATION
* blocks based on the application ID.
*
* STREAMINFO and SEEKTABLE blocks are always parsed and used internally, but
* they still can legally be filtered from the metadata_callback.
*
* \note
* The "set" functions may only be called when the decoder is in the
* state FLAC__STREAM_DECODER_UNINITIALIZED, i.e. after
* FLAC__stream_decoder_new() or FLAC__stream_decoder_finish(), but
* before FLAC__stream_decoder_init(). If this is the case they will
* return \c true, otherwise \c false.
*
* \note
* FLAC__stream_decoder_finish() resets all settings to the constructor
* defaults, including the callbacks.
