 /***********************************************************************
 **
 ** Name: prpoll_err.c
 **
 ** Description: This program tests PR_Poll with sockets.
 **              error reporting operation is tested
 **
 ** Modification History:
 ** 19-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.
