## Detailed Description

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 seekable stream decoder 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 seekable stream decoder module and stream decoder module 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 `true`, otherwise `false`.

Note:
  FLAC__file_decoder_finish() resets all settings to the constructor defaults, including the callbacks.

## Enumeration Type Documentation

enum FLAC__FileDecoderState

State values for a FLAC__FileDecoder

The decoder's state can be obtained by calling FLAC__file_decoder_get_state().

Enumeration values:

  FLAC__FILE_DECODER_OK | The decoder is in the normal OK state.
  FLAC__FILE_DECODER_END_OF_FILE | The decoder has reached the end of the file.
  FLAC__FILE_DECODER_ERROR_OPENING_FILE | An error occurred opening the input file.

  FLAC__FILE_DECODER_SEEK_ERROR | An error occurred while seeking.
  FLAC__FILE_DECODER_SEEKABLE_STREAM_DECODER_ERROR | An error occurred in the underlying seekable stream decoder.
  FLAC__FILE_DECODER_ALREADY_INITIALIZED | FLAC__file_decoder_init() was called when the decoder was already initialized, usually because FLAC__file_decoder_finish() was not called.
  FLAC__FILE_DECODER_INVALID_CALLBACK | FLAC__file_decoder_init() was called without all callbacks being set.
  FLAC__FILE_DECODER_UNINITIALIZED | The decoder is in the uninitialized state.
