| 7 ** name io_timeoutk.c | |
| 8 ** Description:Test socket IO timeouts (kernel level) | |
| 9 ** | |
| 10 ** Modification History: | |
| 11 ** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag. | |
| 12 ** The debug mode will print all of the printfs associated with this test. | |
| 13 ** The regress mode will be the default mode. Since the regress tool limits | |
| 14 ** the output to a one line status:PASS or FAIL,all of the printf statements | |
| 15 ** have been handled with an if (debug_mode) statement. | |
| 16 ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to | |
| 17 ** recognize the return code from tha main program. | |
