Function rsmpeg::ffi::av_adler32_update

pub unsafe extern "C" fn av_adler32_update(
    adler: u64, 
    buf: *const u8, 
    len: u32
) -> u64

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
