It looks right to me, but maybe you'd be better off using the
asmdefs syntax to get your byte offset (36).  The whole point of
that is that asmdef ensures that you get the right offset for
the data in your struct, even if the struct itself changes
layout.  OK, so this is a Windows-defined struct and Windows
tends to be binary compatible, so maybe it's not needed here.
