)

Build the CID part of the ROHC packets.

Parameters
cid_typeThe type of CID in use for the compression context: ROHC_SMALL_CID or ROHC_LARGE_CID
cidThe value of the CID for the compression context
destThe rohc-packet-under-build buffer
dest_sizeThe length of the rohc-packet-under-build buffer
first_positionOUT: 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
