 ** name io_timeoutu.c

 ** Description: Test socket IO timeouts (user level)

 **

 ** 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.
