Global Variable


Predefined CFDictionaryKeyCallBacks structure containing a set of callbacks appropriate for use when the keys of a CFDictionary are all CFString objects, which may be mutable and need to be copied in order to serve as constant keys for the values in the dictionary.


const CFDictionaryKeyCallBacks kCFCopyStringDictionaryKeyCallBacks;


You typically use a pointer to this constant when creating a new dictionary.
