|
**
|
|
|
|
** This server simulates a server running in loopback mode.
|
|
|
|
**
|
|
|
|
** The idea is that a single server is created. The server initially creates
|
|
|
|
** a number of worker threads. Then, with the server running, a number of
|
|
|
|
** clients are created which start requesting service from the server.
|
|
|
|
**
|
|
|
|
**
|
|
|
|
** 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.
