[−][src]Function ffav_sys::av_adler32_update
pub unsafe extern "C" fn av_adler32_update(
adler: c_ulong,
buf: *const u8,
len: c_uint
) -> c_ulong
Calculate the Adler32 checksum of a buffer.
Passing the return value to a subsequent av_adler32_update() call allows the checksum of multiple buffers to be calculated as though they were concatenated.
@param adler initial checksum value @param buf pointer to input buffer @param len size of input buffer @return updated checksum
