XtAppReleaseCacheRefs() 												   XtAppReleaseCacheRefs()

Name
  XtAppReleaseCacheRefs - decrement the reference counts for cached resources obtained from XtCallConverter().

Synopsis
  void XtAppReleaseCacheRefs(app, refs)
	   XtAppContext app;
	   XtCacheRef *refs;

Inputs
  app	    Specifies the application context.

  refs	    Specifies a NULL-terminated array of cache references to be decremented.

Availability
  Release 4 and later.

Description
  XtAppReleaseCacheRefs()  decrements  the  reference  count  for  each XtCacheRef in the NULL-terminated array refs.  If any reference count
  reaches zero, the destructor registered with XtSetTypeConverter() for that resource type, if any, will be called and the  resource  removed
  from the conversion cache.

  An XtCacheRef is a handle to a cached resource value.  It is obtained in a call to XtCallConverter().

Usage
  Applications	and widgets should very rarely need to call this function.  The Intrinsics provide two predefined callbacks which can be reg-
  istered with an XtCacheRef or an array of XtCacheRef	on the destroy callback of a widget or object  to  automatically  call	XtAppRelease-
  CacheRefs() when the resources are no longer needed.	See XtCallbackReleaseCacheRef() and XtCallbackReleaseCacheRefList().

  Additionally,  the function XtConvertAndStore() which is a higher-level interface to resource converters than XtCallConverter() is passed a
  widget or object and automatically registers XtCallbackReleaseCacheRef() on the object's destroy callback if needed.	XtCreateWidget()  may
  also register such callbacks.

Structures
  XtCacheRef is an opaque type.
