Type Definition flac_sys::FLAC__IOCallback_Seek

type FLAC__IOCallback_Seek = Option<unsafe extern "C" fn(handle: FLAC__IOHandle, offset: FLAC__int64, whence: c_int) -> c_int>;

Signature for the seek callback. The signature and semantics mostly match POSIX fseek() WITH ONE IMPORTANT EXCEPTION: the offset is a 64-bit type whereas fseek() is generally 'long' and 32-bits wide.

\param handle The handle to the data source. \param offset The new position, relative to \a whence \param whence \c SEEK_SET, \c SEEK_CUR, or \c SEEK_END \retval int \c 0 on success, \c -1 on error.
