File: SERVER.CPP
Summary: Implementation file for the CServer server-related utility
C++ object. This object encapsulates the server's internal
control of global server object and lock counts.
For a comprehensive tutorial code tour of this module's
contents and offerings see the tutorial DLLSERVE.HTM file.
For more specific technical details on the internal workings
see the comments dispersed throughout the module's source code.
Classes: CServer.
Functions:
Origin: 9-11-95: atrent - Editor-inheritance from COMOBJ.CPP in
the COMOBJ Tutorial Code Sample.
