Write all metadata out to a FLAC stream via callbacks.
(See FLAC__metadata_chain_write() for the details on how padding is
used to write metadata in place if possible.)
This version of the write-with-callbacks function must be used when
FLAC__metadata_chain_check_if_tempfile_needed() returns true. In
this function, you must supply an I/O handle corresponding to the
FLAC file to edit, and a temporary handle to which the new FLAC
file will be written. It is the caller's job to move this temporary
FLAC file on top of the original FLAC file to complete the metadata
edit.
The \a handle must be open for reading and be seekable. The
equivalent minimum stdio fopen() file mode is \c "r" (or \c "rb"
for Windows).
The \a temp_handle must be open for writing. The
equivalent minimum stdio fopen() file mode is \c "w" (or \c "wb"
for Windows). It should be an empty stream, or at least positioned
at the start-of-file (in which case it is the caller's duty to
truncate it on return).
For this write function to be used, the chain must have been read with
FLAC__metadata_chain_read_with_callbacks()/FLAC__metadata_chain_read_ogg_with_callbacks(),
not FLAC__metadata_chain_read()/FLAC__metadata_chain_read_ogg().
Also, FLAC__metadata_chain_check_if_tempfile_needed() must have returned
\c true.
\param chain A pointer to an existing chain.
\param use_padding See FLAC__metadata_chain_write()
\param handle The I/O handle of the original FLAC stream to read.
The handle will NOT be closed after the metadata is
written; that is the duty of the caller.
\param callbacks A set of callbacks to use for I/O on \a handle.
The mandatory callbacks are \a read, \a seek, and
\a eof.
\param temp_handle The I/O handle of the FLAC stream to write. The
handle will NOT be closed after the metadata is
written; that is the duty of the caller.
\param temp_callbacks
A set of callbacks to use for I/O on temp_handle.
The only mandatory callback is \a write.
\assert
\code chain != NULL \endcode
\retval FLAC__bool
\c true if the write succeeded, else \c false. On failure,
check the status with FLAC__metadata_chain_status().
