* \section intro Introduction
*
* This is the documentation for the FLAC C and C++ APIs. It is
* highly interconnected; this introduction should give you a top
* level idea of the structure and how to find the information you
* need. As a prerequisite you should have at least a basic
* knowledge of the FLAC format, documented
* <A HREF="../format.html">here</A>.
*
* \section c_api FLAC C API
*
* The FLAC C API is the interface to libFLAC, a set of structures
* describing the components of FLAC streams, and functions for
* encoding and decoding streams, as well as manipulating FLAC
* metadata in files. The public include files will be installed
* in your include area (for example /usr/include/FLAC/...).
*
* By writing a little code and linking against libFLAC, it is
* relatively easy to add FLAC support to another program. The
* library is licensed under <A HREF="../license.html">Xiph's BSD license</A>.
* Complete source code of libFLAC as well as the command-line
* encoder and plugins is available and is a useful source of
* examples.
*
* Aside from encoders and decoders, libFLAC provides a powerful
* metadata interface for manipulating metadata in FLAC files. It
* allows the user to add, delete, and modify FLAC metadata blocks
* and it can automatically take advantage of PADDING blocks to avoid
* rewriting the entire FLAC file when changing the size of the
* metadata.
*
* libFLAC usually only requires the standard C library and C math
* library. In particular, threading is not used so there is no
* dependency on a thread library. However, libFLAC does not use
* global variables and should be thread-safe.
*
* libFLAC also supports encoding to and decoding from Ogg FLAC.
* However the metadata editing interfaces currently have limited
* read-only support for Ogg FLAC files.
*
* \section cpp_api FLAC C++ API
*
* The FLAC C++ API is a set of classes that encapsulate the
* structures and functions in libFLAC. They provide slightly more
* functionality with respect to metadata but are otherwise
* equivalent. For the most part, they share the same usage as
* their counterparts in libFLAC, and the FLAC C API documentation
* can be used as a supplement. The public include files
* for the C++ API will be installed in your include area (for
* example /usr/include/FLAC++/...).
*
* libFLAC++ is also licensed under
* <A HREF="../license.html">Xiph's BSD license</A>.
*
* \section getting_started Getting Started
*
* A good starting point for learning the API is to browse through
* the <A HREF="modules.html">modules</A>. Modules are logical
* groupings of related functions or classes, which correspond roughly
* to header files or sections of header files. Each module includes a
* detailed description of the general usage of its functions or
* classes.
*
* From there you can go on to look at the documentation of
* individual functions. You can see different views of the individual
* functions through the links in top bar across this page.
*
* If you prefer a more hands-on approach, you can jump right to some
* <A HREF="../documentation_example_code.html">example code</A>.
*
* \section porting_guide Porting Guide
*
* Starting with FLAC 1.1.3 a \link porting Porting Guide \endlink
* has been introduced which gives detailed instructions on how to
* port your code to newer versions of FLAC.
*
* \section embedded_developers Embedded Developers
*
* libFLAC has grown larger over time as more functionality has been
* included, but much of it may be unnecessary for a particular embedded
* implementation. Unused parts may be pruned by some simple editing of
* src/libFLAC/Makefile.am. In general, the decoders, encoders, and
* metadata interface are all independent from each other.
*
* It is easiest to just describe the dependencies:
*
* - All modules depend on the \link flac_format Format \endlink module.
* - The decoders and encoders depend on the bitbuffer.
* - The decoder is independent of the encoder. The encoder uses the
* decoder because of the verify feature, but this can be removed if
* not needed.
* - Parts of the metadata interface require the stream decoder (but not
* the encoder).
* - Ogg support is selectable through the compile time macro
* \c FLAC__HAS_OGG.
*
* For example, if your application only requires the stream decoder, no
* encoder, and no metadata interface, you can remove the stream encoder
* and the metadata interface, which will greatly reduce the size of the
* library.
*
* Also, there are several places in the libFLAC code with comments marked
* with "OPT:" where a #define can be changed to enable code that might be
* faster on a specific platform. Experimenting with these can yield faster
* binaries.

/** \defgroup porting Porting Guide for New Versions
*
* This module describes differences in the library interfaces from
* version to version. It assists in the porting of code that uses
* the libraries to newer versions of FLAC.
*
* One simple facility for making porting easier that has been added
* in FLAC 1.1.3 is a set of \c #defines in \c export.h of each
* library's includes (e.g. \c include/FLAC/export.h). The
* \c #defines mirror the libraries'
* <A HREF="http://www.gnu.org/software/libtool/manual/libtool.html#Libtool-versioning">libtool version numbers</A>,
* e.g. in libFLAC there are \c FLAC_API_VERSION_CURRENT,
* \c FLAC_API_VERSION_REVISION, and \c FLAC_API_VERSION_AGE.
* These can be used to support multiple versions of an API during the
* transition phase, e.g.
*
* \code
* #if !defined(FLAC_API_VERSION_CURRENT) || FLAC_API_VERSION_CURRENT <= 7
* legacy code
* #else
* new code
* #endif
* \endcode
*
* The the source will work for multiple versions and the legacy code can
* easily be removed when the transition is complete.
*
* Another available symbol is FLAC_API_SUPPORTS_OGG_FLAC (defined in
* include/FLAC/export.h), which can be used to determine whether or not
* the library has been compiled with support for Ogg FLAC. This is
* simpler than trying to call an Ogg init function and catching the
* error.

/** \defgroup porting_1_1_2_to_1_1_3 Porting from FLAC 1.1.2 to 1.1.3
* \ingroup porting
*
* \brief
* This module describes porting from FLAC 1.1.2 to FLAC 1.1.3.
*
* The main change between the APIs in 1.1.2 and 1.1.3 is that they have
* been simplified. First, libOggFLAC has been merged into libFLAC and
* libOggFLAC++ has been merged into libFLAC++. Second, both the three
* decoding layers and three encoding layers have been merged into a
* single stream decoder and stream encoder. That is, the functionality
* of FLAC__SeekableStreamDecoder and FLAC__FileDecoder has been merged
* into FLAC__StreamDecoder, and FLAC__SeekableStreamEncoder and
* FLAC__FileEncoder into FLAC__StreamEncoder. Only the
* FLAC__StreamDecoder and FLAC__StreamEncoder remain. What this means
* is there is now a single API that can be used to encode or decode
* streams to/from native FLAC or Ogg FLAC and the single API can work
* on both seekable and non-seekable streams.
*
* Instead of creating an encoder or decoder of a certain layer, now the
* client will always create a FLAC__StreamEncoder or
* FLAC__StreamDecoder. The old layers are now differentiated by the
* initialization function. For example, for the decoder,
* FLAC__stream_decoder_init() has been replaced by
* FLAC__stream_decoder_init_stream(). This init function takes
* callbacks for the I/O, and the seeking callbacks are optional. This
* allows the client to use the same object for seekable and
* non-seekable streams. For decoding a FLAC file directly, the client
* can use FLAC__stream_decoder_init_file() and pass just a filename
* and fewer callbacks; most of the other callbacks are supplied
* internally. For situations where fopen()ing by filename is not
* possible (e.g. Unicode filenames on Windows) the client can instead
* open the file itself and supply the FILE* to
* FLAC__stream_decoder_init_FILE(). The init functions now returns a
* FLAC__StreamDecoderInitStatus instead of FLAC__StreamDecoderState.
* Since the callbacks and client data are now passed to the init
* function, the FLAC__stream_decoder_set_*_callback() functions and
* FLAC__stream_decoder_set_client_data() are no longer needed. The
* rest of the calls to the decoder are the same as before.
*
* There are counterpart init functions for Ogg FLAC, e.g.
* FLAC__stream_decoder_init_ogg_stream(). All the rest of the calls
* and callbacks are the same as for native FLAC.
*
* As an example, in FLAC 1.1.2 a seekable stream decoder would have
* been set up like so:
*
* \code
* FLAC__SeekableStreamDecoder *decoder = FLAC__seekable_stream_decoder_new();
* if(decoder == NULL) do_something;
* FLAC__seekable_stream_decoder_set_md5_checking(decoder, true);
* [... other settings ...]
* FLAC__seekable_stream_decoder_set_read_callback(decoder, my_read_callback);
* FLAC__seekable_stream_decoder_set_seek_callback(decoder, my_seek_callback);
* FLAC__seekable_stream_decoder_set_tell_callback(decoder, my_tell_callback);
* FLAC__seekable_stream_decoder_set_length_callback(decoder, my_length_callback);
* FLAC__seekable_stream_decoder_set_eof_callback(decoder, my_eof_callback);
* FLAC__seekable_stream_decoder_set_write_callback(decoder, my_write_callback);
* FLAC__seekable_stream_decoder_set_metadata_callback(decoder, my_metadata_callback);
* FLAC__seekable_stream_decoder_set_error_callback(decoder, my_error_callback);
* FLAC__seekable_stream_decoder_set_client_data(decoder, my_client_data);
* if(FLAC__seekable_stream_decoder_init(decoder) != FLAC__SEEKABLE_STREAM_DECODER_OK) do_something;
* \endcode
*
* In FLAC 1.1.3 it is like this:
*
* \code
* FLAC__StreamDecoder *decoder = FLAC__stream_decoder_new();
* if(decoder == NULL) do_something;
* FLAC__stream_decoder_set_md5_checking(decoder, true);
* [... other settings ...]
* if(FLAC__stream_decoder_init_stream(
* decoder,
* my_read_callback,
* my_seek_callback, // or NULL
* my_tell_callback, // or NULL
* my_length_callback, // or NULL
* my_eof_callback, // or NULL
* my_write_callback,
* my_metadata_callback, // or NULL
* my_error_callback,
* my_client_data
* ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something;
* \endcode
*
* or you could do;
*
* \code
* [...]
* FILE *file = fopen("somefile.flac","rb");
* if(file == NULL) do_somthing;
* if(FLAC__stream_decoder_init_FILE(
* decoder,
* file,
* my_write_callback,
* my_metadata_callback, // or NULL
* my_error_callback,
* my_client_data
* ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something;
* \endcode
*
* or just:
*
* \code
* [...]
* if(FLAC__stream_decoder_init_file(
* decoder,
* "somefile.flac",
* my_write_callback,
* my_metadata_callback, // or NULL
* my_error_callback,
* my_client_data
* ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something;
* \endcode
*
* Another small change to the decoder is in how it handles unparseable
* streams. Before, when the decoder found an unparseable stream
* (reserved for when the decoder encounters a stream from a future
* encoder that it can't parse), it changed the state to
* \c FLAC__STREAM_DECODER_UNPARSEABLE_STREAM. Now the decoder instead
* drops sync and calls the error callback with a new error code
* \c FLAC__STREAM_DECODER_ERROR_STATUS_UNPARSEABLE_STREAM. This is
* more robust. If your error callback does not discriminate on the the
* error state, your code does not need to be changed.
*
* The encoder now has a new setting:
* FLAC__stream_encoder_set_apodization(). This is for setting the
* method used to window the data before LPC analysis. You only need to
* add a call to this function if the default is not suitable. There
* are also two new convenience functions that may be useful:
* FLAC__metadata_object_cuesheet_calculate_cddb_id() and
* FLAC__metadata_get_cuesheet().
*
* The \a bytes parameter to FLAC__StreamDecoderReadCallback,
* FLAC__StreamEncoderReadCallback, and FLAC__StreamEncoderWriteCallback
* is now \c size_t instead of \c unsigned.

* \brief
* This module describes porting from FLAC 1.1.3 to FLAC 1.1.4.
*
* There were no changes to any of the interfaces from 1.1.3 to 1.1.4.
* There was a slight change in the implementation of
* FLAC__stream_encoder_set_metadata(); the function now makes a copy
* of the \a metadata array of pointers so the client no longer needs
* to maintain it after the call. The objects themselves that are
* pointed to by the array are still not copied though and must be

* \brief
* This module describes porting from FLAC 1.1.4 to FLAC 1.2.0.
*
* There were only very minor changes to the interfaces from 1.1.4 to 1.2.0.
* In libFLAC, \c FLAC__format_sample_rate_is_subset() was added.
* In libFLAC++, \c FLAC::Decoder::Stream::get_decode_position() was added.
*
* Finally, value of the constant \c FLAC__FRAME_HEADER_RESERVED_LEN
* has changed to reflect the conversion of one of the reserved bits
* into active use. It used to be \c 2 and now is \c 1. However the
* FLAC frame header length has not changed, so to skip the proper

*
* In FLAC 1.1.3 it is like this:
*
* \code
* FLAC__StreamDecoder *decoder = FLAC__stream_decoder_new();
* if(decoder == NULL) do_something;
* FLAC__stream_decoder_set_md5_checking(decoder, true);
* [... other settings ...]
* if(FLAC__stream_decoder_init_stream(
* decoder,
* my_read_callback,
* my_seek_callback, // or NULL
* my_tell_callback, // or NULL
* my_length_callback, // or NULL
* my_eof_callback, // or NULL
* my_write_callback,
* my_metadata_callback, // or NULL
* my_error_callback,
* my_client_data
* ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something;
* \endcode
*
* or you could do;
*
* \code
* [...]
* FILE *file = fopen("somefile.flac","rb");
* if(file == NULL) do_somthing;
* if(FLAC__stream_decoder_init_FILE(
* decoder,
* file,
* my_write_callback,
* my_metadata_callback, // or NULL
* my_error_callback,
* my_client_data
* ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something;
* \endcode
*
* or just:
*
* \code
* [...]
* if(FLAC__stream_decoder_init_file(
* decoder,
* "somefile.flac",
* my_write_callback,
* my_metadata_callback, // or NULL
* my_error_callback,
* my_client_data
* ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something;
* \endcode
*
* Another small change to the decoder is in how it handles unparseable
* streams. Before, when the decoder found an unparseable stream
* (reserved for when the decoder encounters a stream from a future
* encoder that it can't parse), it changed the state to
* \c FLAC__STREAM_DECODER_UNPARSEABLE_STREAM. Now the decoder instead
* drops sync and calls the error callback with a new error code
* \c FLAC__STREAM_DECODER_ERROR_STATUS_UNPARSEABLE_STREAM. This is
* more robust. If your error callback does not discriminate on the the
* error state, your code does not need to be changed.
*
* The encoder now has a new setting:
* FLAC__stream_encoder_set_apodization(). This is for setting the
* method used to window the data before LPC analysis. You only need to
* add a call to this function if the default is not suitable. There
* are also two new convenience functions that may be useful:
* FLAC__metadata_object_cuesheet_calculate_cddb_id() and
* FLAC__metadata_get_cuesheet().
*
* The \a bytes parameter to FLAC__StreamDecoderReadCallback,
* FLAC__StreamEncoderReadCallback, and FLAC__StreamEncoderWriteCallback
* is now \c size_t instead of \c unsigned.

* \brief
* This module describes porting from FLAC 1.1.3 to FLAC 1.1.4.
*
* There were no changes to any of the interfaces from 1.1.3 to 1.1.4.
* There was a slight change in the implementation of
* FLAC__stream_encoder_set_metadata(); the function now makes a copy
* of the \a metadata array of pointers so the client no longer needs
* to maintain it after the call. The objects themselves that are
* pointed to by the array are still not copied though and must be
* maintained until the call to FLAC__stream_encoder_finish().

*
* \brief
* This module describes porting from FLAC 1.1.4 to FLAC 1.2.0.
*
* There were only very minor changes to the interfaces from 1.1.4 to 1.2.0.
* In libFLAC, \c FLAC__format_sample_rate_is_subset() was added.
* In libFLAC++, \c FLAC::Decoder::Stream::get_decode_position() was added.
*
* Finally, value of the constant \c FLAC__FRAME_HEADER_RESERVED_LEN
* has changed to reflect the conversion of one of the reserved bits
* into active use. It used to be \c 2 and now is \c 1. However the
* FLAC frame header length has not changed, so to skip the proper
* number of bits, use \c FLAC__FRAME_HEADER_RESERVED_LEN +
* \c FLAC__FRAME_HEADER_BLOCKING_STRATEGY_LEN
*/

*
* The FLAC C API is the interface to libFLAC, a set of structures
* describing the components of FLAC streams, and functions for
* encoding and decoding streams, as well as manipulating FLAC
* metadata in files.
*
* You should start with the format components as all other modules
* are dependent on it.

/** \defgroup flac_callbacks FLAC/callback.h: I/O callback structures
* \ingroup flac
*
* \brief
* This module defines the structures for describing I/O callbacks
* to the other FLAC interfaces.
*
* The purpose of the I/O callback functions is to create a common way
* for the metadata interfaces to handle I/O.
*
* Originally the metadata interfaces required filenames as the way of
* specifying FLAC files to operate on. This is problematic in some
* environments so there is an additional option to specify a set of
* callbacks for doing I/O on the FLAC file, instead of the filename.
*
* In addition to the callbacks, a FLAC__IOHandle type is defined as an
* opaque structure for a data source.

*
* \brief
* This module defines the structures for describing I/O callbacks
* to the other FLAC interfaces.
*
* The purpose of the I/O callback functions is to create a common way
* for the metadata interfaces to handle I/O.
*
* Originally the metadata interfaces required filenames as the way of
* specifying FLAC files to operate on. This is problematic in some
* environments so there is an additional option to specify a set of
* callbacks for doing I/O on the FLAC file, instead of the filename.
*
* In addition to the callbacks, a FLAC__IOHandle type is defined as an
* opaque structure for a data source.
*
* The callback function prototypes are similar (but not identical) to the
* stdio functions fread, fwrite, fseek, ftell, feof, and fclose. If you use
* stdio streams to implement the callbacks, you can pass fread, fwrite, and
* fclose anywhere a FLAC__IOCallback_Read, FLAC__IOCallback_Write, or
* FLAC__IOCallback_Close is required, and a FILE* anywhere a FLAC__IOHandle
* is required. \warning You generally CANNOT directly use fseek or ftell
* for FLAC__IOCallback_Seek or FLAC__IOCallback_Tell since on most systems
* these use 32-bit offsets and FLAC requires 64-bit offsets to deal with
* large files. You will have to find an equivalent function (e.g. ftello),
* or write a wrapper. The same is true for feof() since this is usually
