Should we use exit() in C?

Question

There is question about using exit in C++. The answer discusses that it is not good idea mainly because of RAII, e.g., if exit is called somewhere

Answer 1

You don't have constructors and destructors but you could have resources (e.g. files, streams, sockets) and it is important to close them correctly. A buffer could not be written synchronously, so exiting from the program without correctly closing the resource first, could lead to corruption.
