Okay, you guys are right. What to do? I need these routines
desperately and since I have been fooling around with
my kernel and I am willing to add more stuff to it if this is the only
way to implement them reliably.
Maybe the quetion is, Is there a way to implememnt these routines
under xenix? I really need them. -Thanks.
