Function ffmpeg_sys_next::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
