int av_sha_init	(	struct AVSHA *	context,
		int	bits
	)

Initialize SHA-1 or SHA-2 hashing.

Parameters:

	context	pointer to the function context (of size av_sha_size)
	bits	number of bits in digest (SHA-1 - 160 bits, SHA-2 224 or 256 bits)

Returns:

zero if initialization succeeded, -1 otherwise
