XtSetErrorHandler()													       XtSetErrorHandler()

Name
  XtSetErrorHandler - set the low-level error handler procedure.

Synopsis
  void XtSetErrorHandler(handler)
	 XtErrorHandler handler;

Inputs
  handler   Specifies the new low-level fatal error procedure, which should not return.

Availability
  XtSetErrorHandler() has been superseded by XtAppSetErrorHandler().

Description
  XtSetErrorHandler()  registers the procedure handler as the procedure to be invoked by XtError(). It should display the string it is passed
  and then must terminate the application; if it returns the subsequent behavior of the Intrinsics is undefined.

Usage
  XtSetErrorHandler() has been superseded by XtAppSetErrorHandler(), which performs the same function on  a  per-application  context  basis.
  XtSetErrorHandler()  now calls XtAppSetErrorHandler() passing the default application context created by XtInitialize().  Very few programs
  need multiple application contexts, and you can continue to use XtSetErrorHandler() if you initialize your application with XtInitialize().
  We  recommend,  however,  that you use XtAppInitialize(), XtAppSetErrorHandler(), and the other XtApp*() application context specific func-
  tions.

  See XtAppSetErrorHandler() for more information.
