     or close a display

SYNTAX

     Widget XtOpenApplication(XtAppContext *app_context_return,
          String application_class, XrmOptionDescRec *options,
          Cardinal num_options, int *argc_in_out, String

     Widget XtVaOpenApplication(XtAppContext *app_context_return,
          String application_class, XrmOptionDescRec *options,
          Cardinal num_options, int *argc_in_out, String

          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 argu-
               ment 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 appli-
               cation 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 XtOpen-
     Display 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_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 XtOpenApplication and XtVaOpenApplication respectively.
