In the previous chapter, you learned how to send information across threads of the same process. In this chapter, you will discover how to share data between threads of different processes. We will even share information between applications running on different physical computers.

The Mandelbrot application will now only display results processed by the worker programs. These minions have only one mission: compute the tasks as fast as possible and return a result to your main application.
Here are the topics covered in this chapter:
How two applications can communicate together
Creating a multithreaded TCP server
Reading and writing on a TCP socket
Other IPC techniques like
QSharedMemory,QProcess, and Qt D-BusNetwork serialization using
QDataStreamComputer clustering
Inter-process communication techniques
An IPC (inter-process communication...
