XtAppContext XtCreateApplicationContext(void);

void XtDestroyApplicationContext(XtAppContext *app\_context*);

XtAppContext XtWidgetToApplicationContext(Widget *w*);

# [ARGUMENTS](#ARGUMENTS)

[*app\_context*](#app_context)

Specifies the application context.

[*w*](#w)

Specifies the widget that you want the application context for.

# [DESCRIPTION](#DESCRIPTION)

The **XtCreateApplicationContext** function returns an application context, which is an opaque type. Every application must have at least one application context.

The **XtDestroyApplicationContext** function destroys the specified application context as soon as it is safe to do so. If called from with an event dispatch (for example, a callback procedure), **XtDestroyApplicationContext** does not destroy the application context until the dispatch is complete.

The **XtWidgetToApplicationContext** function returns the application context for the specified widget.

The **XtToolkitInitialize** function initializes the Intrinsics internals. If **XtToolkitInitialize** was previously called it returns immediately.
