Function Documentation

const ITC_QueueItem* ITC_allocW (  unsigned int  size, ITC_NodeID  nid, ITC_TaskID  tid, ITC_QueueID  qid, ITC_ProtID  pid, const TOC *  toc )

Allocate a queue item descriptor and a send buffer. Parameters: size  (in) Size (bytes) of buffer payload to allocate nid  (in) Destination node ID tid  (in) Destination task ID qid  (in) Destination queue ID pid  (in) Protocol ID toc  (in) Time-out control Return values: ITC_ALOCFAIL  Memory allocation failure ITC_FPAGET  Memory allocation from FPA failed ITC_SENDNID  Invalid/unreachable destination node ITC_SENDQID  Invalid/unreachable destination queue ITC_SHRMEM  Shared memory pool stopping/stopped ITC_SUCCESS  Success Warning: Can return NULL if the request could never be satisfied. Allocations currently limited to 2 kByte Allocates a queue-able buffer long enough to accomodate the requested length payload. Note that this is an ITC payload, not a CCSDS payload. When allocating for a CCSDS packet, size must include the CCSDS header (both primary and secondary), the CCSDS payload and (when appropriate) the CCSDS checksum.

Here is the call graph for this function:

void ITC_free (  void *  prm, ITC_QueueItem *  qitem )  [static]

Free a queue item allocated with ITC_allocW(). Parameters: prm  (in) User parameter (queue item's memory pool) qitem  (in) Queue item This is a specific instance of a free routine written to the ITC_cb_Free callback standard. This instance is used in conjunction with the ITC_allocW() method of packet allocation.

void ITC_freeQueueItem (  const struct _ITC_QueueItem *  qitem  )

Free a queue item and it's associated packet. Parameters: qitem  (in) Queue item

unsigned int ITC_send (  const struct _ITC_QueueItem *  qitem  )

Send a queue item to a destination. Parameters: qitem  (in) Queue item to send Return values: ITC_SENDTID  Destination task stopping/stopped ITC_SUCCESS  Success ITC_send() sends a packet to a destination..

Here is the call graph for this function:

unsigned int validSend (  ITC_NodeID  nid, ITC_TaskID  tid, ITC_QueueID  qid, ITC_ProtID  pid )  [static]

Check the send arguments for validity. Parameters: nid  Destination node ID tid  Destination task ID qid  Destination queue ID pid  Protocol ID Return values: ITC_NODERNG  Node out of valid node range ITC_PROTRNG  Protocol out of valid protocol range ITC_QUEURNG  Queue out of valid queue range ITC_TASKRNG  Task out of valid task range ITC_SUCCESS  Success
