XtOpenApplication(3)			   XT FUNCTIONS 		     XtOpenApplication(3)

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 parameters.

       argv_in_out
		 Specifies the command line parameters.

       fallback_resources
		 Specifies resource values to be used if the application class resource file can-
		 not 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 specifica-
		 tion for the created shell widget.

DESCRIPTION
       The XtOpenApplication function calls XtToolkitInitialize followed by XtCreateApplication-
       Context, then calls XtOpenDisplay with display_string NULL and application_name NULL, and
       finally calls XtAppCreateShell 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_con-
       text_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 XtOpen-
       Application terminates the application. If fallback_resources is non-NULL, XtAppSetFall-
       backResources is called with the value prior to calling XtOpenDisplay.

       XtAppInitialize and XtVaAppInitialize have been superceded by XtOpenApplication and XtVa-
       OpenApplication respectively.
