WM_QUIT message

Indicates a request to terminate an application, and is generated when the application calls the PostQuitMessage function. This message causes the GetMessage function to return zero.


#define WM_QUIT                         0x0012

Parameters

wParam

The exit code given in the PostQuitMessage function.

lParam

This parameter is not used.

Return value

Type: LRESULT

This message does not have a return value because it causes the message loop to terminate before the message is sent to the application's window procedure.

Remarks

The WM_QUIT message is not associated with a window and therefore will never be received through a window's window procedure. It is retrieved only by the GetMessage or PeekMessage functions.

Do not post the WM_QUIT message using the PostMessage function; use PostQuitMessage.

Windows 2000 Professional [desktop apps only]
