ARGUMENTS
       app_context_return
                 Specifies the application context.

       application_class
                 Specifies the class name of this application,
                 which usually is the generic name for all
                 instances of this application.

       options   Specifies how to parse the command line for any
                 application-specific resources.  The options
                 argument is passed as a parameter to
                 XrmParseCommand.  For further information, see
                 Xlib - C Language X Interface.

       num_options
                 Specifies the number of entries in the options
                 list.

       argc_in_out
                 Specifies a pointer to the number of command
                 line parameters.

       argv_in_out
                 Specifies the command line parameters.

       fallback_resources
                 Specifies resource valus to be used if the
                 application class resource file cannot be opened
                 or read, or NULL.

       args      Specifies the argument list to override any
                 other resource specification for the created
                 shell widget.

       num_args  Specifies the number of entries in the argument
                 list.

       ...       Specifies the variable argument list to override
                 any other resource specification for the created
                 shell widget.

DESCRIPTION
       The XtAppInitialize function calls XtToolkitInitialize
       followed by XtCreateApplicationContext, then calls
       XtOpenDisplay with display_string NULL and applica-
       tion_name NULL, and finally calls XtAppCreateShell with
       appcation_name NULL, widget_class
       applicationShellWidgetClass, and the specified args and
       num_args and returns the created shell. The modified argc
       and argv returned by XtDisplayInitialize are returned in
       argc_in_out and argv_in_out. If app_context_return is not
       NULL, the created application context is also returned. If
       the display specified by the command line cannot be
       opened, an error message is issued and XtAppInitialize
       terminates the application. If fallback_resources is non-
       NULL, XtAppSetFallbackResources is called with the value
       prior to calling XtOpenDisplay.

       XtAppInitialize and XtVaAppInitialize have been superceded
       by XtOpenApplication and XtVaOpenApplication respectively.
