		GF_SLHeader *	Header,
		u8 *	PDU,
		u32	size,
		u8 **	outPacket,
		u32 *	OutSize
	)

packetizes SL-PDU. If PDU is NULL or size 0, only writes the SL header

Parameters

slConfig	the target SL config descriptor
Header	the SL header for this data block
PDU	the payload to packetize
size	the payload size
outPacket	set to an allocated buffer containing the serialized SL packet - to be destroyed by caller
OutSize	set to the size of the serialized SL packer

gets SL header size

Parameters

slConfig	the target SL config descriptor
Header	the SL header for this data block

Returns

the size of the SL header in bytes

		GF_SLHeader *	Header,
		const u8 *	PDU,
		u32	PDULength,
		u32 *	HeaderLen
	)

depacketizes SL-PDU

Parameters

slConfig	the target SL config descriptor
Header	filled with the decoded SL header
PDU	the SL packet to parse
PDULength	the size of the SL packet
HeaderLen	set to size of the SL header - payload will start at PDU + *HeaderLen
