That's effectively a byte*** parameter. I think you'll have to marshal
that as a `ref IntPtr`, then use Marshal.Copy(), etc.

`static' means "not available for linking from outside this file (or
file that #include this file)". You cannot P/Invoke it.
(And `inline` means that the compiler should inline all calls to the
function, so even if it weren't `static` it might not exist for linking
You'll have to provide a new function that calls this function, and
P/Invoke the new function.
