/* 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.
