XtOpenApplication(3Xt)		 XT FUNCTIONS	       XtOpenApplication(3Xt)



NAME
       XtOpenApplication, XtVaOpenApplication - initialize, open, or close a
       display

SYNTAX
       Widget XtOpenApplication(XtAppContext *app_context_return, String
	      application_class, XrmOptionDescRec *options, Cardinal
	      num_options, int *argc_in_out, String *argv_in_out, String
	      *fallback_resources, WidgetClass widget_class, ArgList args,
	      Cardinal num_args);

       Widget XtVaOpenApplication(XtAppContext *app_context_return, String
	      application_class, XrmOptionDescRec *options, Cardinal
	      num_options, int *argc_in_out, String *argv_in_out, String
	      *fallback_resources, WidgetClass widget_class, ...);

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 parame-
		 ters.

       argv_in_out
		 Specifies the command line parameters.

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

       widget_class
		 Specifies the widget class of the shell to be created.

       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 XtOpenApplication function calls XtToolkitInitialize followed by
       XtCreateApplicationContext, then calls XtOpenDisplay with dis-
       play_string NULL and application_name NULL, and finally calls XtAp-
       pCreateShell with application_name NULL, the specified widget_class,
       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
       XtOpenApplication 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 XtOpen-
       Application and XtVaOpenApplication respectively.
