CServerMailslot & CClientMailslot v1.18 C++ wrapper classes for Win32 Mailslots

These 2 classes provides a clean C++ interface to the Win32 IPC mechanism called mailslots. They are very similar to the more common "Named pipe" IPC mechanism. Unlike named pipes, mailslots use datagrams. A datagram is a small packet of information that the network sends along the wire. Like a radio or television broadcast, a datagram offers no confirmation of receipt; there is no way to guarantee that a datagram has been received.

Mailslots can broadcast messages within a domain. If several processes in a domain each create a mailslot using the same name, every message that is addressed to that mailslot and sent to the domain is received by the participating processes. Because one process can control both a server and client mailslot handle, applications can easily implement a simple message-passing facility within a domain.

 

The enclosed zip file contains the source code for the 2 classes and also includes a VC 2005 solution to build a demonstration program called WinNotify. It is based on the old MS WinPopup utility as shown below:
