8 | ** Name: prpoll_err.c |
9 | ** |
10 | ** Description: This program tests PR_Poll with sockets. |
11 | ** error reporting operation is tested |
12 | ** |
13 | ** Modification History: |
14 | ** 19-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. |
