WM_QUIT

The WM_QUIT message indicates a request to terminate an application and is generated when the application calls the PostQuitMessage function. It causes the GetMessage function to return zero.

WM_QUIT 
nExitCode = (int) wParam;   // exit code 
 

Parameters

nExitCode

Value of wParam. Specifies the exit code given in the PostQuitMessage function.

Return Values
