This Qt C++ application demonstrates how to share memory between processes. The client GUI application and the server executable share memory through QSharedMemory. The example has two shared memory areas: one for the client to command the server, and another for the server to respond to the client. The example application has been tested to work on Maemo and Symbian with the Qt 4.6.2 release.
Important classes: QSharedMemory, QProcess.
