Displays a message box and terminates the application
_WinAPI_FatalAppExit ( $sMessage )
|$sMessage||The string that is displayed in the message box|
An application calls FatalAppExit only when it is not capable of terminating any other way.
FatalAppExit may not always free an application's memory or close its files, and it may cause a general failure of the system.
An application that encounters an unexpected error should terminate by freeing all its memory and returning from its main message loop.
