struct CFunctionPointer<T> The family of C function pointer types. In imported APIs, T is a Swift function type such as (Int)->String. Though not directly useful in Swift, CFunctionPointer<T> can be used to safely pass a C function pointer, received from one C or Objective-C API, to another C or Objective-C API. Inheritance CVarArgType, DebugPrintable, Equatable, Hashable, NilLiteralConvertible View Protocol Hierarchy → Import import Swift Initializers init() Create a nil instance. Declaration init() init(_:) Reinterpret the bits of value as CFunctionPointer<T>. Warning: This is a fundamentally unsafe operation, equivalent to unsafeBitCast(value, CFunctionPointer<T>.self) Declaration init(_ value: COpaquePointer) init(nilLiteral:) Create an instance initialized with nil. Declaration init(nilLiteral: ()) Instance Variables var debugDescription: String A textual representation of self, suitable for debugging. Declaration var debugDescription: String { get } var hashValue: Int The hash value. Axiom: x == y implies x.hashValue == y.hashValue Note: the hash value is not guaranteed to be stable across different invocations of the same program. Do not persist the hash value across program runs. Declaration var hashValue: Int { get } Instance Methods func encode() Transform self into a series of machine words that can be appropriately interpreted by C varargs Declaration func encode() -> [Word]
