Function Documentation

int BIUSIM_init (  int    argc, char **    argv )  [static]

Initialize application resources. This function peforms the following actions to setup the BIUSIM application for operation: Verifies the correct number of command line arguments. Creates the BIUSIM_hkpRecvSocket socket. Creates the BIUSIM_eventRecvSocket socket. Binds BIUSIM_hkpRecvSocket to port number BIU_PORT_DAQ_HKP. Binds BIUSIM_eventRecvSocket to port number BIU_PORT_DAQ_EVENT. Lookup the IP address of the GSE host (command line argument #1). Creates the BIUSIM_sendSocket socket. Parameters: argc  The number of command line arguments. argv  Pointers to the command line arguments. Return values: 0  Success. -1  Failure because a resource could not be created or initialized.

void BIUSIM_send (  int    size )  [static]

Send a telemetry packet to the GSE host. After verification, sends the CCSDS telemetry packet in BIUSIM_pktBuf out on BIUSIM_sendSocket. Parameters: size  The packet size as reported by UDP.

int main (  int    argc, char **    argv )

After initializing resources, the main application function listens for incomming telemetry packets on BIUSIM_hkpRecvSocket. After verifcation, the CCSDS header is stripped and the packet data is written to BIUSIM_sendSocket. Parameters: argc  The number of command line arguments. argv  Pointers to the command line arguments.
