XtAppSetErrorHandler()					XtAppSetErrorHandler()

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

Synopsis
  XtErrorHandler XtAppSetErrorHandler(app_context, handler)
	 XtAppContext app_context;
	 XtErrorHandler handler;

Inputs
  app_context
	    Specifies the application context.

  handler   Specifies  the  new	 fatal	error procedure, which should not
	    return.

Returns
  A pointer to the previously installed low-level error handler.

Description
  XtAppSetErrorHandler() registers the procedure handler  in  app_context
  as  the  procedure to be invoked by XtAppError().  It returns a pointer
  to the previously installed low-level	 fatal	error  handler.	  handler
  must	terminate  the application; if it returns the subsequent behavior
  of the Intrinsics is undefined.

  The default low-level error  handler	provided  by  the  Intrinsics  is
  _XtDefaultError().   On  POSIX-based	systems, it prints the message to
  standard error and terminates the application.

Usage
  Note that application-context-specific error	handling  is  not  imple‐
  mented on many systems.  Most implementations will have just one set of
  error handlers.  If they are set for	different  application	contexts,
  the one performed last will prevail.
