NAME
       XtAppInitialize, XtVaAppInitialize - initialize, open, or
       close a display

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

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

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.

       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
       application_name NULL, widget_class applicationShellWid-
       getClass, 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 cre-
       ated 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, XtAppSet-
       FallbackResources is called with the value prior to call-
       ing XtOpenDisplay.

       XtAppInitialize and XtVaAppInitialize have been superceded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