CClosureRef

public struct CClosureRef : CClosureProtocol

The CClosureRef type acts as a lightweight Swift reference to an underlying GCClosure instance. It exposes methods that can operate on this data type through CClosureProtocol conformance. Use CClosureRef only as an unowned reference to an existing GCClosure instance.

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

  • ptr
    Untyped pointer to the underlying `GCClosure` instance.
    

    For type-safe access, use the generated, typed pointer _ptr property instead.

    Declaration

    Swift

    public let ptr: UnsafeMutableRawPointer!

CClosure Record

  • Designated initialiser from the underlying C data type

    Declaration

    Swift

  • Designated initialiser from a constant pointer to the underlying C data type

    Declaration

    Swift

    init(_ p: UnsafePointer<GCClosure>)
  • Conditional initialiser from an optional pointer to the underlying C data type

    Declaration

    Swift

    @inlinable
    init!(_ maybePointer: UnsafeMutablePointer<GCClosure>?)
  • Conditional initialiser from an optional, non-mutable pointer to the underlying C data type

    Declaration

  • Conditional initialiser from an optional gpointer

    Declaration

    Swift

    @inlinable
    init!(gpointer g: gpointer?)
  • Conditional initialiser from an optional, non-mutable gconstpointer

    Declaration

    Swift

  • Reference intialiser for a related type that implements CClosureProtocol

    Declaration

    Swift

    @inlinable
    init<T>(_ other: T) where T : CClosureProtocol
  • Unsafe typed initialiser. Do not use unless you know the underlying data type the pointer points to conforms to CClosureProtocol.

    Declaration

    Swift

    @inlinable
    init<T>(cPointer: UnsafeMutablePointer<T>)
  • Unsafe typed initialiser. Do not use unless you know the underlying data type the pointer points to conforms to CClosureProtocol.

    Declaration

    Swift

    @inlinable
    init<T>(constPointer: UnsafePointer<T>)
  • Unsafe untyped initialiser. Do not use unless you know the underlying data type the pointer points to conforms to CClosureProtocol.

    Declaration

    Swift

    @inlinable
    init(mutating raw: UnsafeRawPointer)
  • Unsafe untyped initialiser. Do not use unless you know the underlying data type the pointer points to conforms to CClosureProtocol.

    Declaration

    Swift

    @inlinable
    init(raw: UnsafeMutableRawPointer)
  • Unsafe untyped initialiser. Do not use unless you know the underlying data type the pointer points to conforms to CClosureProtocol.

    Declaration

    Swift

    @inlinable
    init(opaquePointer: OpaquePointer)
