[−][src]Function mp4parse_capi::mp4parse_get_track_count
#[no_mangle]pub unsafe extern "C" fn mp4parse_get_track_count(
parser: *const Mp4parseParser,
count: *mut u32
) -> Mp4parseStatus
Return the number of tracks parsed by previous mp4parse_read()
call.
Safety
This function is unsafe because it dereferences both the parser and count
raw pointers passed into it. Callers should ensure the parser pointer
points to a valid Mp4parseParser
, and that the count pointer points an
appropriate memory location to have a u32
written to.
