Question

What is message loop example in windows programming?

Answer 1

loop means doing it again and again

Answer 2

In response to the WM_DESTROY message, the window calls the PostQuitMessage function, which puts a WM_QUIT message (which is defined as 0) into the message queue. When the message loop (described above) gets the WM_QUIT message, it breaks from the loop, and returns the value from the PostQuitMessage function.
