CFSetApplierFunction
Prototype of a callback function that may be applied to every value in a set.
Declaration
typealias CFSetApplierFunction = (UnsafeRawPointer?, UnsafeMutableRawPointer?) -> VoidParameters
- value:
The current value in a set.
- context:
The program-defined context parameter given to the apply function.
Discussion
This callback is passed to the CFSetApplyFunction(_:_:_:) function which iterates over the values in a set and applies the behavior defined in the applier function to each value in a set.
