    CONSOLE APPLICATION : CSMailslotServer Project Overview
========================================================================

/////////////////////////////////////////////////////////////////////////////
Use:

Mailslot is a mechanism for one-way inter-process communication in the local
machine or across the computers in the intranet. Any clients can store 
messages in a mailslot. The creator of the slot, i.e. the server, retrieves 
the messages that are stored there:

Client (GENERIC_WRITE) ---> Server (GENERIC_READ)

This sample demonstrates a mailslot server, \\.\mailslot\HelloWorld. It first
creates such a mailslot, then it reads the new messages in the slot every 
five seconds.


/////////////////////////////////////////////////////////////////////////////
Project Relation:

CSMailslotClient -> CSMailslotServer
CSMailslotClient is the client end of the mailslot.

CSMailslotServer - CppMailslotServer
