Function Documentation

unsigned int VSBC_bcPktCmdRxSend (  VSBC_BC *  bc, void *  pkt, VSBC_BC_Pkt_Free *  freeHandler, void *  freeArg, const TOC *  timeout )

Send a CCSDS telecommand receive packet. Places a CCSDS telecommand receive packet on the bus controller output queue. The packet will be sent when bandwidth becomes available. Parameters: bc  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.

Here is the call graph for this function:

unsigned int VSBC_bcPktCmdTxFree (  VSBC_BC *  bc, void *  pkt )

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

Here is the call graph for this function:

unsigned int VSBC_bcPktCmdTxRecv (  VSBC_BC *  bc, void **  pkt, const TOC *  timeout )

Receive a CCSDS telecommand transmit packet. Waits for a new CCSDS telecommand transmit packet on the bus controller 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 VSBC_bcPktCmdTxFree(). Parameters: bc  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.

Here is the call graph for this function:

unsigned int VSBC_bcPktTelemFree (  VSBC_BC *  bc, void *  pkt )

Free a CCSDS telemtry packet. Returns a CCSDS telemetry packet buffer to the driver. This function should be called for every telemetry packet received from the function VSBC_bcPktTelemRecv(). Parameters: bc  A device descriptor. pkt  A pointer to the packet buffer to free. Returns: A CTDB MSG code.

Here is the call graph for this function:

unsigned int VSBC_bcPktTelemRecv (  VSBC_BC *  bc, void **  pkt, const TOC *  timeout )

Receive a CCSDS telemetry packet. Waits for a new CCSDS telemetry packet on the bus controller input queue. The function will place a pointer to the new packet buffer in pkt if everything is working correctly. The user should return the packet buffer to the driver by calling VSBC_bcPktTelemFree(). Parameters: bc  A device descriptor. pkt  Holds a pointer to the telemetry packet. timeout  The time to wait for a packet on the queue. Returns: A CTDB MSG code.
