Function Documentation

c_add_cid()

static uint8_t c_add_cid ( const rohc_cid_t  cid )

static

Set an add-CID value.

Add-CID is needed when using small CIDs.

Parameters

cid	The small CID to set

Returns

The add-CID byte

code_cid_values()

int code_cid_values	(	const rohc_cid_type_t	cid_type,
		const rohc_cid_t	cid,
		uint8_t *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
