WinCancelShutdown

function cancels a request for an application to [[shutdown|shut down]].

#define INCL_WINMESSAGEMGR /* Or use INCL_WIN, INCL_PM, Also in COMMON section */
#include 

HMQ     hmq;            /*  Handle of message queue for current thread. */
BOOL    fCancelAlways;  /*  Cancellation control. */
BOOL    rc;             /*  Success indicator. */

rc = WinCancelShutdown(hmq, fCancelAlways);

Parameters

hmq (HMQ) - input. Handle of message queue for current thread. 
fCancelAlways (BOOL) - input. Cancellation control. 
  TRUE   No WM_QUIT message should be placed on this queue during system shutdown. 
  FALSE  The applications ignore any outstanding WM_QUIT messages already sent to it, but a message should be sent during other system shutdowns. 

Returns

 rc (BOOL) Success indicator. 
    TRUE  Successful completion 
    FALSE  Error occurred. 

Notes

On a system shutdown, each message queue is normally posted a WM_QUIT message. An application can handle this message in one of two ways:

• Destroy its message queue using [[WinDestroyMsgQueue]] (hmq) or,
• Call [[WinCancelShutdown]](hmq, FALSE)
