The PostQuitMessage function indicates to Windows that a thread has made a request to terminate (quit). It is typically used in response to a WM_DESTROY message.
VOID PostQuitMessage(
|
int nExitCode |
// exit code |
|
); |
This function does not return a value.
The PostQuitMessage function posts a WM_QUIT message to the thread’s message queue and returns immediately; the function simply indicates to the system that the thread is requesting to quit at some time in the future.
When the thread retrieves the WM_QUIT message from its message queue, it should exit its message loop and return control to Windows. The exit value returned to Windows must be the wParam parameter of the WM_QUIT message.
