HOWTO: Detect Closure of Command Window from a Console App


The information in this article applies to:

  • Microsoft Win32 Application Programming Interface (API), used with:
    • the operating system: Microsoft Windows NT, versions 3.1, 3.5, 4.0
    • the operating system: Microsoft Windows 2000


Win32 console applications run in a command window. So that the console application can detect when the console is closing, register a console control handler and look for the following values in your case statement:

   CTRL_CLOSE_EVENT     User closes the console
   CTRL_LOGOFF_EVENT    User logs off
   CTRL_SHUTDOWN_EVENT  User shuts down the system 

For an example, see the CONSOLE sample. For more information, see the entry for SetConsoleCtrlhandler() in the Win32 application programming interface (API) reference.
