Instance Property


A prototype for a function callback that provides a description of the data pointed to by the info field. In implementing this function, return a reference to a CFString object that describes your allocator, particularly some characteristics of your program-defined data. You may set this function pointer to NULL, in which case Core Foundation will provide a rudimentary description.


var copyDescription: CFAllocatorCopyDescriptionCallBack!
