+/***********************************************************************
+**  1997 - Netscape Communications Corporation
+**
+** Name: prselect_err.c
+**
+** Description: tests PR_Select with sockets Error condition functions.
+**
+** 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.
