Function Documentation

unsigned int SUMT_rtPktCmdRxFree (  SUMT_RT *  rt, void *  pkt )

Free a CCSDS command receive packet. Returns a CCSDS telecommand input packet buffer to the driver. This function should be called for every command packet received from the function SUMT_rtPktCmdRxRecv(). Parameters: rt  A device descriptor. pkt  A pointer to the packet buffer to free. Returns: A CTDB MSG code.

unsigned int SUMT_rtPktCmdRxRecv (  SUMT_RT *  rt, void **  pkt, const TOC *  timeout )

Receive an incomming CCSDS command receive packet. Waits for a new CCSDS telecommand receive packet on the remote terminal input queue. The function will place a pointer to the new packet buffer in pkt. The user should return the packet buffer to the driver by calling SUMT_rtPktCmdRxFree(). Parameters: rt  A device descriptor. pkt  Holds a pointer to the telecommand packet. timeout  The time to wait for a packet on the queue. Returns: A CTDB MSG code.

unsigned int SUMT_rtPktCmdTxSend (  SUMT_RT *  rt, void *  pkt, SUMT_RT_Pkt_Free *  freeHandler, void *  freeArg, const TOC *  timeout )

Send an outgoing CCSDS command transmit packet. Places a CCSDS telecommand packet on the remote terminal output queue. The packet will be sent when bandwidth becomes available. Parameters: rt  A device descriptor. pkt  A pointer to the packet to send. The packet buffer should start with a properly formatted CCSDS packet header. freeHandler  The function to be called after the packet has been sent. freeArg  A user argument to be passed to the freeHandler function. timeout  The time to wait for a packet on the queue. Returns: A CTDB MSG code.

unsigned int SUMT_rtPktTelemSend (  SUMT_RT *  rt, void *  pkt, SUMT_RT_Pkt_Free *  freeHandler, void *  freeArg, SUMT_RT_Priority  priority, const TOC *  timeout )

Send a CCSDS telemetry packet. Places a CCSDS telemetry packet on one of the remote terminal output queues. The packet will be sent when bandwidth becomes available. Parameters: rt  A device descriptor. pkt  A pointer to the packet to send. The packet buffer should start with a properly formatted CCSDS packet header. freeHandler  The function to be called after the packet has been sent. freeArg  A user argument to be passed to the freeHandler function. priority  The priority of the packet: SUMT_RT_PRIORITY_HIGH or SUMT_RT_PRIORITY_LOW. timeout  The time to wait for a packet on the queue. Returns: A CTDB MSG code.
