/***********************************************************************
**  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.
** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
**                      recognize the return code from tha main program.
