+/***********************************************************************
+**
+** Name: prpoll_norm.c
+**
+** Description: This program tests PR_Poll with sockets.
+** Normal operation are 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.
