- /** defgroup flac_file_decoder FLAC/file_decoder.h: file decoder interface
- * ingroup flac_decoder
- *
- * brief
- * This module contains the functions which implement the file
- * decoder.
- *
- * The basic usage of this decoder is as follows:
- * - The program creates an instance of a decoder using
- * FLAC__file_decoder_new().
- * - The program overrides the default settings and sets callbacks for
- * writing, error reporting, and metadata reporting using
- * FLAC__file_decoder_set_*() functions.
- * - The program initializes the instance to validate the settings and
- * prepare for decoding using FLAC__file_decoder_init().
- * - The program calls the FLAC__file_decoder_process_*() functions
- * to decode data, which subsequently calls the callbacks.
- * - The program finishes the decoding with FLAC__file_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__file_decoder_delete().
- *
- * The file decoder is a trivial wrapper around the
- * link flac_seekable_stream_decoder seekable stream decoder endlink
- * meant to simplfy the process of decoding from a standard file. The
- * file decoder supplies all but the Write/Metadata/Error callbacks.
- * The user needs only to provide the path to the file and the file
- * decoder handles the rest.
- *
- * Like the seekable stream decoder, seeking is exposed through the
- * FLAC__file_decoder_seek_absolute() method. At any point after the file
- * decoder has been initialized, the user can call this function to seek to
- * an exact sample within the file. Subsequently, the first time the write
- * callback is called it will be passed a (possibly partial) block starting
- * at that sample.
- *
- * The file decoder also inherits MD5 signature checking from the seekable
- * stream decoder. If this is turned on before initialization,
- * FLAC__file_decoder_finish() will report when the decoded MD5 signature
- * does not match the one stored in the STREAMINFO block. MD5 checking is
- * automatically turned off if there is no signature in the STREAMINFO
- * block or when a seek is attempted.
- *
- * Make sure to read the detailed descriptions of the
- * link flac_seekable_stream_decoder seekable stream decoder module endlink
- * and link flac_stream_decoder stream decoder module endlink
- * since the file decoder inherits much of its behavior from them.
- *
- * note
- * The "set" functions may only be called when the decoder is in the
- * state FLAC__FILE_DECODER_UNINITIALIZED, i.e. after
- * FLAC__file_decoder_new() or FLAC__file_decoder_finish(), but
- * before FLAC__file_decoder_init(). If this is the case they will
- * return c true, otherwise c false.
- *
- * note
- * FLAC__file_decoder_finish() resets all settings to the constructor
- * defaults, including the callbacks.
