How does one attach video memory (say, 0xB8000...) to the address
space of a process via the shared memory IPC facilities (the AT&T-
style ones) in the SCO Xenix environment? This can be done under
Microport UNIX by using shmcreate.

There is a standard ioctl to do it, if you don't insist on shm. -- bill davidsen (wedu@ge-crd.arpa) {uunet | philabs | seismo}!steinmetz!crdos1!davidsen "Stupidity, like virtue, is its own reward" -me
