SYNTAX

              String application_class, XrmOptionDescRec
              *options, Cardinal num_options, int *argc_in_out,
              String *argv_in_out, String *fallback_resources,

       Widget XtVaOpenApplication(XtAppContext *app_con-
              text_return, String application_class, XrmOptionDe-
              scRec *options, Cardinal num_options, int
              *argc_in_out, String *argv_in_out, String *fall-
              back_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 XrmParseC-
                 ommand.  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 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 display_string NULL and applica-
       tion_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
       XtOpenApplication terminates the application. If fall-
       back_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.
