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.

Function Documentation

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).

Here is the call graph for this function:

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.
