Function Documentation

int main (  int  argc, char *  argv[] )

Driver / test routine to exercise the DI code. Note: Uses contents of "DI194_PORT" if set Main. Open the port, init the card, do some daq. Too: -p port parsing, will need for USB serial. getopt! Parameters: argc  Argc as passed by shell argv  Argv as passed by shell Returns: 0 All is good Non-zero All is not good Definition at line 337 of file di_test.c. References di_open(), do_exit, sighandler(), and user_loop().

void sighandler (  int  signal  )

Control-break handler. Sets global flag to indicate exit request. Assumes Installed in interrupt chain by someone else Parameters: signal  Signal number Returns: void No return value Date: 3/25/02 Definition at line 304 of file di_test.c. References do_exit.

int user_loop (  const int  COMM_FD  )

Main loop - read kbd commands, execute same, loop. Note: Code copied from Joe Link's simple-ftp-client.c Author: pfh Date: 4-16-02 Assumes Port opened and ready to go Definition at line 87 of file di_test.c.
