** 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.
