Of course you are supposed to know that. For calling them from real
mode, you'ld have to know it, too. There's no particular difference in
handling, here.

If you don't even know if the routine you're calling is an interrupt
handler (terminating with iret) or not, you may have to re-think if
you know enough about it to use it, at all.

(In case of doubt, use the non-iret version).
