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