Parameters:

cid	The small CID to set

Returns:

The add-CID byte

int code_cid_values	(	struct c_context *	context,
		unsigned char *	dest,
		int	dest_size,
		int *	first_position
	)

Build the CID part of the ROHC packets.

Parameters:

context	The compression context
dest	The rohc-packet-under-build buffer
dest_size	The length of the rohc-packet-under-build buffer
first_position	OUT: The position of the first byte to be completed by other functions

Returns:

The position in the rohc-packet-under-build buffer
