/***********************************************************************
**
** Name: prpoll_to.c
**
** Description: This program tests PR_Poll with sockets.
**              Timeout operation is tested
**
** Modification History:
** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
**           The debug mode will print all of the printfs associated with this
*test.
**           The regress mode will be the default mode. Since the regress tool
*limits
**           the output to a one line status:PASS or FAIL,all of the printf
*statements
**           have been handled with an if (debug_mode) statement.
** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been
*updated to
**          recognize the return code from tha main program.
