C/C++ way of working with these things requires specifying the start and
end point using pointer arithmetic, which is pretty cumbersome considering
how often it is needed. I think what Ian said is probably the most complete
way to deal with it.
But probably you can also do it using the unsafe library, if you can grab
the length vector from the C/C++ side, convert to an untyped unsafe
pointer, and then back to array: [length]byte, and you won't have any
issues from attempting to write past the allocated end of the buffer. Then
you can use it like a regular slice by using name[:]. Of course if
performance is critical you may not want to do that as it is likely to
trigger a copy operation when you didn't mean it.
