unsigned long av_adler32_update | ( | unsigned long | adler, |
const uint8_t * | buf, | ||
unsigned int | 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.
adler | initial checksum value |
buf | pointer to input buffer |
len | size of input buffer |
