Function Documentation

av_md5_alloc()

struct AVMD5 * av_md5_alloc

(

void

)

		size_t	len )

Update hash value.

Parameters

ctx	hash function context
src	input data to update hash with
len	input data length

av_md5_final()

void av_md5_final	(	struct AVMD5 *	ctx,
		uint8_t *	dst )

Finish hashing and output digest value.

Parameters

ctx	hash function context
