|
|---|
| 41 | **
|
|---|
| 42 | ** Description: This program tests PR_Poll with sockets.
|
|---|
| 43 | ** Normal operation are tested
|
|---|
| 44 | **
|
|---|
| 45 | ** Modification History:
|
|---|
| 46 | ** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
|
|---|
| 47 | ** The debug mode will print all of the printfs associated with this test.
|
|---|
| 48 | ** The regress mode will be the default mode. Since the regress tool limits
|
|---|
| 49 | ** the output to a one line status:PASS or FAIL,all of the printf statements
|
|---|
| 50 | ** have been handled with an if (debug_mode) statement.
|
|---|
| 51 | ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
|
|---|
| 52 | ** recognize the return code from tha main program.
