SYNTAX #include <X11/Intrinsic.h>
Widget XtAppInitialize(XtAppContext* app_context_return, const char *application_class, XrmOptionDescRec* options, Cardinal num_options, int *argc_in_out, char **argv_in_out, String *fallback_resources, ArgList args, Cardinal num_args);
Widget XtVaAppInitialize(XtAppContext* app_context_return, const char *application_class, XrmOptionDescRec* options, Cardinal num_options, int *argc_in_out, char **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 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 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.

DESCRIPTION The XtAppInitialize function calls XtToolkitInitialize followed by XtCreateApplicationContext, then calls XtOpenDisplay with display_string NULL and application_name NULL, and finally calls XtAppCreateShell with application_name NULL, widget_class applicationShellWidgetClass, and the specified args and num_args and XtOpenDisplay.
XtAppInitialize and XtVaAppInitialize have been superceded by XtOpenApplication and XtVaOpenApplication respectively.
