1.10 +**
1.11 +** This server simulates a server running in loopback mode.
1.12 +**
1.13 +** The idea is that a single server is created. The server initially creates
1.14 +** a number of worker threads. Then, with the server running, a number of
1.15 +** clients are created which start requesting service from the server.
1.16 +**
1.17 +**
1.18 +** Modification History:
1.19 +** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
1.20 +** The debug mode will print all of the printfs associated with this test.
1.21 +** The regress mode will be the default mode. Since the regress tool limits
1.22 +** the output to a one line status:PASS or FAIL,all of the printf statements
1.23 +** have been handled with an if (debug_mode) statement.
1.24 +** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
1.25 +** recognize the return code from tha main program.
