XtSetWarningHandler()													     XtSetWarningHandler()

Name
  XtSetWarningHandler - set the low-level warning handler procedure.

Synopsis
  void XtSetWarningHandler(handler)
	 XtErrorHandler handler;

Inputs
  handler   Specifies the new low-level warning procedure.

Availability
  XtSetWarningHandler() has been superseded by XtAppSetWarningHandler().

Description
  XtSetWarningHandler()  registers  the  procedure  handler as the procedure to be invoked by XtWarning(). It should display the string it is
  passed and return.

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  XtSetWarningHandler() has been superseded by XtAppSetWarningHandler(), which performs the same function on a per-application context basis.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

  See XtAppSetWarningHandler() for more information.
