Function Documentation

void CCSDS_apidDscConstruct (  CCSDS_apidDsc *  dsc, void *  ctx, unsigned short int  apid, unsigned char *  buf, unsigned int  buf_size )

Constructs (initializes) an CCSDS_apidDsc, an APID descriptor. Parameters: dsc  The descriptor to construct/initialize ctx  User provided context parameter apid  The apid used as a key to identify this descriptor buf  A buffer to receive the data for this apid buf_size  The size, in bytes, of buf. This needs to be as large as the biggest CCSDS packet (including data that spans multiple packets).

CCSDS_apidDsc* CCSDS_apidDscFind (  CCSDS_apidDscTbl *  tbl, const CCSDS_istreamHdr *  hdr )

Built-in method to locate the descriptor associated with the specified APID as read from the header. Return values: Non-NULL,the  descriptor NULL,error,either  the descriptor with the specified APID does not exist or the APID cannot be gotten from the header because the header is unreadable (rare) Parameters: tbl  The table to search hdr  The CCSDS header containing the APID to locate

int CCSDS_apidDscRegister (  CCSDS_apidDscTbl *  tbl, CCSDS_apidDsc *  dsc, void *  ctx, unsigned short int  apid, unsigned char *  buf, unsigned int  buf_size )

Registers an APID descriptor. Return values: 0,Successful  -1,APID  has been previously registered Parameters: tbl  The apid table dsc  The descriptor to construct/initialize ctx  User provided context parameter apid  The apid used as a key to identify this descriptor buf  A buffer to receive the data for this apid buf_size  The size, in bytes, of buf. This needs to be as large as the biggest CCSDS packet (including data that spans multiple packets).

void CCSDS_apidDscReset (  CCSDS_apidDsc *  dsc  )

Resets the specified APID descriptor to its initial state. This routine is used mainly for error recovery. Parameters: dsc  The descriptor to reset

static __inline CCSDS_apidDscNode insert (  CCSDS_apidDscNode *  head, CCSDS_apidDscNode *  node )  [static]

Inserts an APID descriptor on the que. Returns: The previous last descriptor on the que Parameters: head  The que head node  The node to insert on the que
