8 ** name io_timeoutu.c
9 ** Description: Test socket IO timeouts (user level)
10 **
11 ** Modification History:
12 ** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
13 **           The debug mode will print all of the printfs associated with this test.
14 **           The regress mode will be the default mode. Since the regress tool limits
15 **           the output to a one line status:PASS or FAIL,all of the printf statements
16 **           have been handled with an if (debug_mode) statement.
17 ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
18 **          recognize the return code from tha main program.
