That is true. Even when it will be there, I was thinking about naming it in a different way. To emphasize the fact that this API is not portable. I don't know when I'm going to implement it. On windows it's supposed to give access to https://msdn.microsoft.com/en-us/library/windows/desktop/ms683499(v=vs.85).aspx. Directly. Which is far from how it works on linux.

With this in mind, I've put a workaround in my code, since if this is implemented in a different enough way, it likely won't be what I want.
