Swift: gettimeofday and Unsafe Pointers

Question

The code in Swift

...
var time:timeval?
gettimeofday(UnsafePointer, UnsafePointer<()>) // this is the method expansion before filling in any         


        

Answer 1

I know one way to do it and this is as follows:

var time:timeval = timeval(tv_sec: 0, tv_usec: 0)
gettimeofday(&time, nil)

I had to initialize time with something so there actually was a struct at the address &time pointed to.
