- * ingroup flac_encoder
- *
- * brief
- * This module contains the functions which implement the file
- * encoder.
- *
- * The basic usage of this encoder is as follows:
- * - The program creates an instance of an encoder using
- * FLAC__file_encoder_new().
- * - The program overrides the default settings using
- * FLAC__file_encoder_set_*() functions.
- * - The program initializes the instance to validate the settings and
- * prepare for encoding using FLAC__file_encoder_init().
- * - The program calls FLAC__file_encoder_process() or
- * FLAC__file_encoder_process_interleaved() to encode data, which
- * subsequently writes data to the output file.
- * - The program finishes the encoding with FLAC__file_encoder_finish(),
- * which causes the encoder to encode any data still in its input pipe,
- * rewind and write the STREAMINFO metadata to file, and finally reset
- * the encoder to the uninitialized state.
- * - The instance may be used again or deleted with
- * FLAC__file_encoder_delete().
- *
- * The file encoder is a wrapper around the
- * link flac_seekable_stream_encoder seekable stream encoder endlink which supplies all
- * callbacks internally; the user need specify only the filename.
- *
- * Make sure to read the detailed description of the
- * link flac_seekable_stream_encoder seekable stream encoder module endlink since the
- * link flac_stream_encoder stream encoder module endlink since the
- * file encoder inherits much of its behavior from them.
- *
- * note
- * The "set" functions may only be called when the encoder is in the
- * state FLAC__FILE_ENCODER_UNINITIALIZED, i.e. after
- * FLAC__file_encoder_new() or FLAC__file_encoder_finish(), but
- * before FLAC__file_encoder_init(). If this is the case they will
- * return c true, otherwise c false.
- *
- * note
- * FLAC__file_encoder_finish() resets all settings to the constructor
- * defaults.
