Function Documentation

unsigned int ITC_allocCmdConfirm (  ITC_QueueItem **  quack, ITC_Task *  task, WCT_time  qtim, const char *  cmd )

Allocate a confirmation packet for a spacecraft telecommand. Parameters: quack  (i/o) Packet to be allocated task  (in) Task handle qtim  (in) Time command dequeued cmd  (in) Pointer to CCSDS telecommand Return values: ITC_ALOCFAIL  Memory allocation failure ITC_SUCCESS  Success

Here is the call graph for this function:

unsigned int ITC_sendCmdConfirm (  const ITC_QueueItem *  quack, ITC_Task *  task, unsigned int  scb, WCT_time  xtim, unsigned int  status )

Send a telecommand execution status reponse. Parameters: quack  (in) Packet already allocated task  (in) Task handle scb  (in) Spacecraft broadcast APID flag xtim  (in) Time execution completed status  (in) Command completion code Return values: ITC_SENDTID  Destination task stopping/stopped ITC_SUCCESS  Success

Here is the call graph for this function:

unsigned int ITC_setCmdConfirm (  ITC_TaskID  tid, ITC_CmdClass  scb, ITC_CmdAction  fwd, ITC_CmdLevel  new, ITC_CmdLevel *  old )

Set the command confirmation level for a task. Parameters: tid  (in) Task ID scb  (in) Spacecraft broadcast APID flag fwd  (in) Task acting as forwarding agent flag new  (in) New command confirmation level old  (in) Old command confirmation level Return values: ITC_PARMRNG  E Parameter out of range ITC_SUCCESS  Success ITC_TASKCROS  E Task pointer check failed ITC_TASKRNG  E Task ID out of range ITC_TASKNULL  E No entry in task table for task ITC_setCmdLevel() sets one of the command confirmation levels for a task. There are four levels that can be controlled, arranged as a two-by-two matrix. The first element of the matrix is whether the command belongs to the class "spacecraft broadcast" (parameter scb). The second element of the matrix is whether the task is acting as a forwarding agent (parameter fwd). Thus the call ITC_setCmdReponse( tid, ITC_CMD_NORMAL, ITC_ACT_FORWARD, ITC_LVL_ERROR, &old ); would mean "for task <tid>, set the command confirmation level to ITC_LVL_ERROR when forwarding non-broadcast spacecraft commands".
