Function zstd_sys::ZSTD_getFrameContentSize [−] [src]

pub unsafe extern "C" fn ZSTD_getFrameContentSize(
    src: *const c_void, 
    srcSize: usize
) -> c_ulonglong

ZSTD_getFrameContentSize() : * src should point to the start of a ZSTD encoded frame * srcSize must be at least as large as the frame header. A value greater than or equal * to ZSTD_frameHeaderSize_max is guaranteed to be large enough in all cases. * @return : decompressed size of the frame pointed to be src if known, otherwise * - ZSTD_CONTENTSIZE_UNKNOWN if the size cannot be determined * - ZSTD_CONTENTSIZE_ERROR if an error occurred (e.g. invalid magic number, srcSize too small)
