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 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. See Also XtAppReleaseCacheRefs(1), XtCallbackReleaseCacheRefList(1), XtCallConverter(1), XtConvertAndStore(1). Xt - Resource Management XtCallbackReleaseCacheRef()
