Function Documentation

static unsigned int control_rx (  void *  prm, const ITC_QueueItem *  qitem, void *  pay, unsigned int  len )  [static]

Process messages arriving on the control queue. Parameters: prm  (in) User context parameter qitem  (in) Queue item to process pay  (in) Queue item payload len  (in) Queue item payload length control_rx() is the callback routine for any traffic arriving on the control queue. For now, that's CPU status records and ITC configuration records coming from the EPUs.

static LHK_PacketStatus LCM_capture (  unsigned int *  sav, unsigned int  abas, unsigned int  aidx, unsigned int  seq, unsigned char *  out )  [static]

Copy housekeeping packets from the LCM packet database. Parameters: sav  (in) User parameter (update counter of last packet copy) abas  (in) Base of APID table (ITC_K_APID_HOUSE or ITC_K_APID_DIAG) aidx  (in) APID index seq  (in) CCSDS sequence count out  (in) Output buffer (beginning of CCSDS telemetry header) Returns: A member of the LHK_PacketStatus enumeration

unsigned int LCM_houseInitializeSIU (  LCM_Control *  ctl  )

Initialize the housekeeping function (specific to SIU). Parameters: ctl  (in) LCM control block LCM_houseInitializeSIU() builds up the SIU specific elements for providing housekeeping information.
