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 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 function calls followed by then calls with display_string NULL and application_name NULL, and finally calls with application_name NULL, widget_class and the specified args and num_args and returns the created shell. The modified argc and argv returned by 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 terminates the application. If fallback_resources is non-NULL, is called with the value prior to calling
