Detailed Description

Byte swap library for CCSDS data structures.

Author:

D.L. Wood

The CCSDS native format is big-endian. This library allows users to insert and extract fields from these structures in native format on little-endian machines. The functions allow for machine-independent code.

void CCSDS_swapPktHdr	(	const void *	inHdr,
		void *	outHdr,
		CCSDS_Pkt_Type	type
	)

Byte swap a LAT CCSDS packet header.

Byte swaps a CCSDS packet header for little-endian machines.

Parameters:

	inHdr	A pointer to the input packet header.
	outHdr	A pointer to the output packet header buffer.
	type	The packet type (CCSDS_PKT_TYPE_CMD or CCSDS_PKT_TYPE_TELEM).

void CCSDS_swapPriHdr	(	const void *	inHdr,
		void *	outHdr
	)

Byte swap a CCSDS packet primary header.

Byte swaps a CCSDS packet primary header for little-endian machines.

Parameters:

	inHdr	A pointer to the input packet header.
	outHdr	A pointer to the output packet header buffer.
