1.10 +** name io_timeoutk.c
1.11 +** Description:Test socket IO timeouts (kernel level)
1.12 +**
1.13 +** Modification History:
1.14 +** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
1.15 +** The debug mode will print all of the printfs associated with this test.
1.16 +** The regress mode will be the default mode. Since the regress tool limits
1.17 +** the output to a one line status:PASS or FAIL,all of the printf statements
1.18 +** have been handled with an if (debug_mode) statement.
1.19 +** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
1.20 +** recognize the return code from tha main program.
