XtRemoveTimeOut()														 XtRemoveTimeOut()

Name
  XtRemoveTimeOut - unregister a timeout procedure.

Synopsis
  void XtRemoveTimeOut(id)
	 XtIntervalId id;

Inputs
  id	    Identifies the timeout interval and the timeout callback to be removed.

Description
  XtRemoveTimeOut()  unregisters the timeout callback identified by id.  id is the handle returned by the call to XtAppAddTimeOut() that reg-
  istered the timeout interval and the procedure.

Usage
  Note that timeouts are automatically removed once they expire and the callback has been called; therefore, you often do not  need  to  call
  XtRemoveTimeOut().   On  the	other hand, if you need user input within a specified amount of time, for example, then you should register a
  timeout callback, and if the input arrives before the timeout callback is called, then you should remove the timeout callback  so  that  it
  isn't called when the application is not expecting it.

Structures
  The XtIntervalId structure is defined as follows:

     typedef unsigned long XtIntervalId;

  XtTimerCallbackProc(2).

XtAppAddTimeOut - register a procedure to be called when a specified time elapses.

Synopsis
  XtIntervalId XtAppAddTimeOut(app_context, interval, proc, client_data)
	 XtAppContext app_context;
	 unsigned long interval;
	 XtTimerCallbackProc proc;
	 XtPointer client_data;

Inputs
  app_context
	    Specifies the application context in which the timer is to be set.

  interval  Specifies the time interval in milliseconds.

  proc	    Specifies the procedure that is to be called when the time expires.  See XtTimerCallbackProc(2).

  client_data
	    Specifies data to be passed to proc when it is called.

Returns
  A handle of type XtIntervalId that can be used to unregister the timeout procedure with XtRemoveTimeOut().

Description
  XtAppAddTimeOut()  registers, in application context app_context, a procedure proc, to be called by XtAppNextEvent() with client_data after
  interval milliseconds elapse.  The procedure is called once and automatically unregistered; it will not be called repeatedly every interval
  milliseconds.

  See XtTimerCallbackProc(2) for an explanation of how to write a timer callback.

Usage
  Timer  callbacks  are  automatically unregistered after they are triggered.  To have a callback called at a regular interval, call XtAppAd-
  dTimeOut() again from within the timer callback.

  A timer callback can be explicitly unregistered before it is invoked by calling XtRemoveTimeOut() with the XtIntervalId  returned  by  this
  function.

Structures
  The XtIntervalId type is defined as follows:

     typedef unsigned long XtIntervalId;
