Name
XtVaAppInitialize - initialize the X Toolkit internals, using varargs argument style.
Synopsis
Widget XtVaAppInitialize(app_context_return, application_class, options, num_options, argc_in_out, argv_in_out, fallback_resources, ...,
NULL)
XtAppContext *app_context_return;
String application_class;
XrmOptionDescList options;
Cardinal num_options;
int *argc_in_out; /* was type Cardinal * in Release 4 */
String *argv_in_out;
String *fallback_resources;
Inputs
application_class
Specifies the class name of the application.
options Specifies the command line options table.
num_options Specifies the number of entries in options.
argc_in_out Specifies a pointer to the number of command line arguments. This argument was a Cardinal * in Release 4, and is an int *
in Release 5.
argv_in_out Specifies the command line arguments array.
fallback_resources
Specifies resource values to be used if the application class resource file cannot be opened, or NULL.
..., NULL A NULL-terminated variable-length list of resource name/value pairs to override any other resource specifications for the
created shell.
Outputs
app_context_return
Returns the application context, if non-NULL.
Returns
A toplevel shell widget of class applicationShellWidgetClass.
Availability
Release 4 and later.
Description
XtVaAppInitialize() initializes the Toolkit internals, creates an application context, opens and initializes a display, and creates the
initial application shell. It is identical to XtAppInitialize() except that the args array of resource names and values and the num_args
argument of that function are replaced with a NULL-terminated variable-length argument list.
See XtAppInitialize() for more information on this function. See XtVaSetValues() for more information on using variable-length argument
lists to specify resources.
