# XtCreateApplicationContext(3x)

create, destroy, and obtain an application context

## NAME

XtCreateApplicationContext, XtDestroyApplicationContext, XtWidgetToApplicationContext, XtToolkitInitialize - create, destroy, and obtain an application context

## SYNTAX

XtAppContext XtCreateApplicationContext(void);

void XtDestroyApplicationContext(XtAppContext *app\_context*,

XtAppContext XtWidgetToApplicationContext(Widget *w*);

void XtToolkitInitialize(void);

## ARGUMENTS

- *app\_context*

  Specifies the application context.

- *w*

  Specifies the widget .

## 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.
