What's the best way to declare an empty SafeHandle?

What's the best way to declare an empty SafeHandle when this parameter is ignored (for example, in CallNextHookEx)?

I believe you can pass null to the friendly overload which will handle it correctly. (Unlike how traditional p/invoke has worked.)

Thanks, in these methods it is really possible to pass null to the SafeHandle place and it will be correctly processed (an empty structure will be passed). I guess I didn't notice it because of this issue (I'm already so used to nullable annotations)

In addition, if calling the extern method itself, you can pass in default as the value so the native code gets a 0.
