| 8 | ** Name: prpoll_to.c |
| 9 | ** |
| 10 | ** Description: This program tests PR_Poll with sockets. |
| 11 | ** Timeout operation is tested |
| 12 | ** |
| 13 | ** Modification History: |
| 14 | ** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag. |
| 15 | ** The debug mode will print all of the printfs associated with this test. |
| 16 | ** The regress mode will be the default mode. Since the regress tool limits |
| 17 | ** the output to a one line status:PASS or FAIL,all of the printf statements |
| 18 | ** have been handled with an if (debug_mode) statement. |
| 19 | ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to |
| 20 | ** recognize the return code from tha main program. |
