If you're very sure about that, you're very wrong.

"write" is quite happy to be passed a pointer to an array of structure elements
(which is what that call does).  You're better off handing it a "char *", as
that's what "write" is defined to take as a second argument (i.e., the second
argument should be cast to "char *"), but on some machines, including Suns,
all pointers have the same representation so you can get away with that
sort of thing.  You shouldn't *rely* on being able to get away with it, though.
