- * Win9xConHook.dll - a hook proc to clean up Win95/98 console behavior.
- *
- * It is well(?) documented by Microsoft that the Win9x HandlerRoutine
- * hooked by the SetConsoleCtrlHandler never receives the CTRL_CLOSE_EVENT,
- * CTRL_LOGOFF_EVENT or CTRL_SHUTDOWN_EVENT signals.
- *
- * It is possible to have a second window to monitor the WM_ENDSESSION
- * message, but the close button still fails..
- *
- * There is a 16bit polling method for the close window option, but this
- * is CPU intensive and requires thunking.
- *
- * Attempts to subclass the 'tty' console fail, since that message thread
- * is actually owned by the 16 bit winoldap.mod process, although the
- * window reports it is owned by the process/thread of the console app.
- *
- * Win9xConHook is thunks the WM_CLOSE and WM_ENDSESSION messages,
- * first through a window hook procedure in the winoldap context, into
- * a subclass WndProc, and on to a second hidden monitor window in the
- * console application's context that dispatches them to the console app's
- * registered HandlerRoutine.
