In Swift 2.2, I could do the following:
var cublasHandle : COpaquePointer = nil
let status = cublasCreate_v2(&cublasHandle)
Where cublasCreate_v2 is a C function that takes a pointer, and then
initializes some memory at that address.
I haven't been able to figure out an equivalent in Swift 3. Any
suggestions, especially to documentation, would be greatly appreciated.
Thanks,

In Swift 3, COpaquePointer was renamed to OpaquePointer, and nullable pointers are represented by optionals:
SE-0055 – Make unsafe pointer nullability explicit using Optional
https://github.com/apple/swift-evolution/blob/master/proposals/0055-optional-unsafe-pointers.md
So the following should work in Swift 3:
var cublasHandle: OpaquePointer?
let status = cublasCreate_v2(&cublasHandle)
