Type Alias FLAC__StreamDecoderEofCallback

pub type FLAC__StreamDecoderEofCallback = Option<unsafe extern "C" fn(decoder: *const FLAC__StreamDecoder, client_data: *mut c_void) -> FLAC__bool>;

Signature for the EOF callback.

A function pointer matching this signature may be passed to FLAC__stream_decoder_init*_stream(). The supplied function will be called when the decoder needs to know if the end of the stream has been reached.

Here is an example of a EOF callback for stdio streams: FLAC__bool eof_cb(const FLAC__StreamDecoder *decoder, void *client_data) \code { FILE file = ((MyClientData)client_data)->file; return feof(file)? true : false; } \endcode

\note In general, FLAC__StreamDecoder functions which change the state should not be called on the \a decoder while in the callback.

\param decoder The decoder instance calling the callback. \param client_data The callee’s client data set through FLAC__stream_decoder_init_*(). \retval FLAC__bool \c true if the currently at the end of the stream, else \c false.
