      XtAppContext \fIapp_context\fP;
.LP
XtAppContext XtWidgetToApplicationContext(\fIw\fP)

.SH ARGUMENTS
.IP \fIapp_context\fP 1i
Specifies the application context.

.IP \fIw\fP 1i
Specifies the widget \*(Wi.
.SH DESCRIPTION
The
.ZN XtCreateApplicationContext
function returns an application context,
which is an opaque type.
Every application must have at least one application context.
.LP
The
.ZN 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),
.ZN XtDestroyApplicationContext
does not destroy the application context until the dispatch is complete.
.LP
The
.ZN XtWidgetToApplicationContext
function returns the application context for the specified widget.
.LP
The semantics of calling
.ZN XtToolkitInitialize
more than once are undefined.
