XtCallbackReleaseCacheRef()			   XtCallbackReleaseCacheRef()

Name
  XtCallbackReleaseCacheRef  -	callback  function  to	release	 a cached
  resource value.

Synopsis
  void XtCallbackReleaseCacheRef(object, client_data, call_data)
	   Widget object;
	   XtPointer client_data;
	   XtPointer call_data;

Inputs
  object    Specifies the object with which the resource is associated.

  client_data
	    Specifies the conversion cache entry to be released.

  call_data Is ignored.

Availability
  Release 4 and later.

Description
  XtCallbackReleaseCacheRef()  casts  its  client_data	argument  to   an
  XtCacheRef,  places  it  in  a  NULL-terminated array of XtCacheRef and
  passes this array to XtAppReleaseCacheRefs().	  XtAppReleaseCacheRefs()
  decrements  the reference count on the specified object in the resource
  conversion cache, and if the count reaches zero it removes  the  object
  from the cache and calls the appropriate destructor procedures.

  XtCallbackReleaseCacheRef()  is  a convenience procedure designed to be
  registered on the destroy callback list of a widget or object (which is
  why it has  third, unused argument).

Usage
  XtCacheRef  values  are  returned from calls to XtCallConverter().  The
  higher-level converter function XtConvertAndStore() performs	the  con‐
  version  and	automatically  registers  this	function  on the object's
  destroy callback list if necessary.

  To release an array  of  XtCacheRef,	you  can  use  XtCallbackRelease‐
  CacheRefList().

Structures
  XtCacheRef is an opaque type.
