AVAdler av_adler32_update ( AVAdler  adler,
const uint8_t *  buf,
size_t  len 
)

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.

Parameters
adlerinitial checksum value
bufpointer to input buffer
lensize of input buffer
