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 con-
  version 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 XtCallbackReleaseCacheRefList().

Structures
  XtCacheRef is an opaque type.
