pointers, depending on the element types. All the discussion below
about Go pointers applies not just to pointer types, but also to other
types that include Go pointers.

All Go pointers passed to C must point to pinned Go memory. Go pointers
passed as function arguments to C functions have the memory they point to
implicitly pinned for the duration of the call. Go memory reachable from
