Communication using Shared Memory between VC++ and Qt applications

问题

I am using FileMapping for implementing shared memory concept in a C++ windows form application and QSharedMemory in Qt application.

I want to read data written by C++ form application using FileMapping technique, in Qt application using QsharedMemory.

Is it possible? If not please suggest appropriate methods to implement this feature.

回答1:

I'm not quite sure of the detail of your implementation, however I would suggest that a better more uniform way to approach this would be by using boost::InterProcess - which provides mechanisms that could be used in both processes and then utilize common code.

The other reason is that the library provides mechanisms for synchronisation and other IPC mechanisms that may be useful in the future.
