Function flac_sys::FLAC__metadata_simple_iterator_get_block_length

pub unsafe extern "C" fn FLAC__metadata_simple_iterator_get_block_length(
    iterator: *const FLAC__Metadata_SimpleIterator
) -> c_uint

Get the length of the metadata block at the current position. This avoids reading the actual block data which can save time for large blocks.

\param iterator A pointer to an existing initialized iterator. \assert \code iterator != NULL \endcode \a iterator has been successfully initialized with FLAC__metadata_simple_iterator_init() \retval unsigned The length of the metadata block at the current iterator position. The is same length as that in the metadata block header, i.e. the length of the metadata body that follows the header.
