 **

 ** 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.
