Detailed Description

Context ID (CID) routines.

Function Documentation

int ROHC_EXPORT code_cid_values	(	const rohc_cid_type_t	cid_type,
		const int	cid,
		unsigned char *const	dest,
		const size_t	dest_size,
		size_t *const	first_position
	)

Build the CID part of the ROHC packets.

Parameters:

cid_type	The type of CID in use for the compression context: ROHC_SMALL_CID or ROHC_LARGE_CID
cid	The value of the CID for 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 in case of success, -1 in case of error
