Dear i do not understand why the first example works and the second
segfault. Thanks

Jesus christ, sorry about that my keyboard script went crazy and posted that.
What I was going to say is it's likely a mismatch of the struct sizes.
In the second example you are dereferencing the pointer on the D size,
which does a field-by-field copy of the pointed-to struct. But D will

Scratch that, in X11 apparently the Display structure is an incomplete
type (so sizeof won't work). This means you most probably *have* to
use pass it around as an opaque pointer. It's kind of odd because you
can still access some of its fields (so it's not totally opaque), but
you can't do
