Function Documentation

BFU RLD_decode	(	BFU	bfu,
		const unsigned int *	buf,
		unsigned int *	new_pos,
		int	cnt
	)

Decodes the run-length encoded value from the input bit stream.

Returns:

The decoded value and updated cur value (only of interest to pass on)

Parameters:

	bfu	The decoding context (contains the current word being decoded + the current decoding bit position).
	buf	The bit buffer
	new_pos	Returned as a pointer to the new position
	cnt	The number of bits in the output word. This must match the value used when encoding the value. This must be a value between 1 and 32.
