CClosureProtocol

public protocol CClosureProtocol

A GCClosure is a specialization of GClosure for C function callbacks.

The CClosureProtocol protocol exposes the methods and properties of an underlying GCClosure instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see CClosure. Alternatively, use CClosureRef as a lighweight, unowned reference if you already have an instance you just want to use.

  • ptr

    Untyped pointer to the underlying GCClosure instance.

    Declaration

    Swift

    var ptr: UnsafeMutableRawPointer! { get }
  • _ptr Default implementation

    Typed pointer to the underlying GCClosure instance.

    Default Implementation

    Return the stored, untyped pointer as a typed pointer to the GCClosure instance.

    Declaration

    Swift

    var _ptr: UnsafeMutablePointer<GCClosure>! { get }
  • Required Initialiser for types conforming to CClosureProtocol

    Declaration

    Swift

    init(raw: UnsafeMutableRawPointer)
