michael@0: ** Name: prpoll_norm.c
michael@0: **
michael@0: ** Description: This program tests PR_Poll with sockets.
michael@0: **              Normal operation are tested
michael@0: **
michael@0: ** Modification History:
michael@0: ** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
michael@0: **	         The debug mode will print all of the printfs associated with this test.
michael@0: **			 The regress mode will be the default mode. Since the regress tool limits
michael@0: **           the output to a one line status:PASS or FAIL,all of the printf statements
michael@0: **			 have been handled with an if (debug_mode) statement.
michael@0: ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
michael@0: **			recognize the return code from tha main program.
