Is there any way how i can write bytes to a NativePtr?

CPointerVarOf<COpaquePointer>(nativePtr)

gives me this Exception: Native interop types constructors must not be called directly I need a CValueRef<*> for memcpy

Not at my computer right now, but there should be an extension that converts nativePtr to Long, and one that converts Long to CPointer.

Thank you. You are right this exists and works great.
