XtAppSetWarningHandler()			      XtAppSetWarningHandler()

Name
  XtAppSetWarningHandler - set the low-level warning handler.

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

Inputs
  app_context
	    Specifies the application context.

  handler   Specifies the new nonfatal error procedure.

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

Description
  XtAppSetWarningHandler() registers the procedure handler in app_context
  as the procedure to be invoked by XtAppWarning().  It returns a pointer
  to the previously installed low-level warning handler.

  The  default	low-level  warning  handler provided by the Intrinsics is
  _XtDefaultWarning().	On POSIX-based systems, it prints the message  to
  standard error and returns to the caller.

Usage
  Note	that  application-context-specific  error and warning handling is
  not implemented 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.
