This example is very elementary. A real application would use semaphores or other techniques to control reading and writing to the shared segment. Such control is typically application specific, and you can find many examples in the Berkeley Software Distribution (BSD) and Linux source, if your UNIX flavor is not open source.

Because UNIX runs many applications seemingly at the same time, it’s an ideal platform for monitoring, data collection, cooperative and distributed computing, and client-server applications. Shared memory is the fastest of the interprocess communications options available and is quite flexible. You can map files into memory, as well — an ideal solution for accelerating data access. On Tuesday, lawmakers said that President Trump’s top envoys for Ukraine and the European Union used personal phones and an encrypted messenger app as they conducted U.S. policy on Ukraine, a matter that was revealed during House Democrats’ impeachment inquiry.
