I am absolutely no expert in C++, but I was under the impression that while it's
highly likely, it's by no means guaranteed that size_t can hold a pointer.
IIRC if a platform has segmented memory then this assumption could break.
In any case, uintptr_t should be available on your target compilers no? If so,
that sounds like the better choice to me.
I may be showing my inexperience, so feel free to ignore the above if it's
That said, as a humble Boost user, native_handle() returning void* sounds a bit
iffy to me. Why is it a pointer if it does not point to anything but should
rather be casted to the appropriate type by the user?
