Function name : FatalAppExit

Group: Error Handling - Library: kernel32

The FatalAppExit function displays a message box and terminates the application when the message box is closed.

Code examples:

Terminating VFP application using the FatalAppExit

Declaration:

VOID FatalAppExit(
  UINT uAction,          // reserved
  LPCTSTR lpMessageText  // display string
);

FoxPro declaration:

DECLARE FatalAppExit IN kernel32;
	INTEGER uAction,;
	STRING  lpMessageText

Parameters:

uAction Reserved; must be zero.

lpMessageText [in] Pointer to a null-terminated string that is displayed in the message box.

Return value:

This function does not return a value.

Comments:

Even the name of this function I feel some evil in it. Hardly a reason exists to use it. In the succession of the good old QUIT, ExitProcess, TerminateProcess, PostQuitMessage etc. this function can be only the last resort.

I recollect an old joke about a computer frozen so deep that it took to reboot a power station.
