Changing *data.data would be undefined behaviour. Don't do it.
Once data is typed as immutable, it must not change anymore. By
casting you're side-stepping the type system, so that you have
to
make sure of such things yourself.
Hm. I'm not planning to change data.data, of course, but I was
worried (and curious) about potential safety issues. I suppose I
could convert short* to short[] > idup it > pass a reference to
the C function (that expects short*). However, I want to avoid
this, because there shouldn't be any additional operations (it's
a (near) real time system).
