- /* nsINativeAppSupport
- *
- * This "pseudo" (in the XPCOM sense) interface provides for
- * platform-specific general application support:
- * o It manages the details of the simple DDE communication
- * supported on the Win32 platform (it is the addition of this
- * item that prompted the creation of this interface.
- *
- * Due to the nature of the beast, this interface is not a full-blown
- * XPCOM component. The primary reason is that objects that implement
- * this interface generally must be operational *before* XPCOM (or any
- * of the rest of Mozilla) are initialized. As a result, this
- * interface is instantiated by somewhat unconventional means.
- *
- * To create the implementor of this interface, you call the function
- * NS_CreateNativeAppSupport. This is done in the startup code
- * in nsAppRunner.cpp
- *
- * The interface provides these functions:
- * start - You call this to inform the native app support that the
- * application is starting. In addition, it serves as a
- * query as to whether the application should continue to
- * run.
- *
- * If the returned boolean result is PR_FALSE, then the
- * application should exit without further processing. In
- * such cases, the returned nsresult indicates whether the
- * reason to exit is due to an error or not.
- *
- * Win32 Note: In the case of starting a second instance
- * of this executable, this function will return
- * PR_FALSE and nsresult==NS_OK. This means that
- * the command line arguments have been
- * successfully passed to the instance of the
- * application acting as a DDE server.
- *
- * stop - You call this to inform the native app support that the
- * application *wishes* to terminate. If the returned boolean
- * value is PR_FALSE, then the application should continue
- * (as if there were still additional top-level windows open).
- *
- * Win32 Note: If this is the instance of the application
- * acting as the DDE server, and there are current
- * DDE conversations active with other instances
- * acting as DDE clients, then this function will
- * return PR_FALSE.
- *
- * quit - Like Stop, but this method *forces* termination (or more
- * precisely, indicates that the application is about to be
- * terminated regardless of what a call to Stop might have
- * returned.
- *
- * This method is intended to be called when the user selects
- * the "Quit" option (close all windows and exit).
- *
- * Win32 Note: Stop is problematic in the case of "Quit" (close
- * all windows and exit the application) because
- * either we don't Quit or (potentially) we lose
- * requests coming from other instances of the
- * application. The strategy is to give preference
- * to the user's explicit Quit request. In the
- * unlikely event that a request is pending from
- * another instance of the application, then such
- * requests are essentially ignored. This is
- * roughly equivalent to handling that request by
- * opening a new window, followed by immediately
- * closing it. Since this is the same as if the
- * request came in immediately before the Quit
- * call (versus immediately after it), no harm.
- *
- * There is an exposure here: Upon return from this
- * function, any DDE connect request (for Mozilla)
- * will fail and other instances of the application
- * will start up as a DDE server. In that case,
- * those instances may do things that conflict with
- * the subsequent shutting down of the instance that
- * is quitting. For this reason, the call to Quit
- * should be deferred as long as possible.
- *
- * onLastWindowClosing - Called when the last window is closed. Used as a
- * "soft" shutdown, passwords are flushed.
