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.

Parameters:

	adler	initial checksum value
	buf	pointer to input buffer
	len	size of input buffer

Returns:

updated checksum
