I'm not sure why this was addressed specifically to me, but your
problem is that the second and third parameters to
i386_get_ioperm() are supposed to be *pointers* to integers.  Note
that i386_get_ioperm() is supposed to tell *you* what the port
permission bits are, not the other way around.  I suggest you take
a look at the manual page more carefully.

Also, I don't have anything to do with i386_get_ioperm(), and
standards@ is not the appropriate list for this kind of inquiry.
Please try questions@ next time.
