Cast a Swift struct to UnsafeMutablePointer<Void>
As far as I know, the shortest way is:
var myStruct = TheStruct()var address = withUnsafeMutablePointer(&myStruct) {UnsafeMutablePointer<Void>($0)}But, why you need this? If you want pass it as a parameter, you can (and should):
func foo(arg:UnsafeMutablePointer<Void>) { //...}var myStruct = TheStruct()foo(&myStruct)
Most of the method prototypes have been changed as Swift evolved over the years. Here is the syntax for Swift 5:
var struct = TheStruct() var unsafeMutablePtrToStruct = withUnsafeMutablePointer(to: &struct) { $0.withMemoryRebound(to: TheStruct.self, capacity: 1) { (unsafePointer: UnsafeMutablePointer<TheStruct>) in unsafePointer } }
