I think you need to read up C basics on pointers to structures and their
components. When you write |(* _mc).s| then that's not a cast but a
access to the component of the struct. But because that reads weird and
is used very often, C has the -> operator for this, so write |_mc->s|
instead. (You should usually also ensure that _mc is valid before
dereferencing it like this.)

But I guess all this is pretty off-topic for this list.
