int Ns_HtuuDecode	(	char *	input,
		unsigned char *	output,
		int	outputlen
	)

----------------------------------------------------------------------

Ns_HtuuDecode --

Decode a string.

Results: Number of binary bytes decoded.

Side effects: Decoded characters are placed in output which must be large enough for the result, i.e., (3 + (len * 3) / 4) bytes.

----------------------------------------------------------------------

Skip leading space, if any.

Determine the maximum length of output bytes.

Decode every four input bytes.

Decode remaining 2 or 3 bytes.

int Ns_HtuuEncode	(	unsigned char *	input,
		unsigned int	len,
		char *	output
	)

----------------------------------------------------------------------

Ns_HtuuEncode --

Encode a string.

Results: Number of bytes placed in output.

Side effects: Encoded characters are placed in output which must be large enough for the result, i.e., (1 + (len * 4) / 3) bytes.

----------------------------------------------------------------------

Convert every three input bytes into four output characters.

Convert and pad any remaining bytes.
