* @file SPIPE_Test.cpp
*
* This is a simple test of Named Pipes that uses
* ACE_SPIPE_Acceptor and ACE_SPIPE_Connector classes. The test
* forks two processes or spawns two threads (depending upon the
* platform) and then executes the client and server allowing
* them to use the named pipe to exchange data. No user input is
* required as far as command line arguments are concerned.
