Doesn't BSD4.3+ have shared mem and semaphores? Steven's Adv.
Programming says that BSD has shared mem (sys/shm.h). And even tho
Steven's says that BSD4.3+ doesn't have semaphores (sys/sem.h) FreeBSD
1.1.5.1 does have both of these header files, and they appear to be
SVID compliant. Mind you, I haven't USED these things, and I am not
qualified to do the kind of kernel hacking you appear to be doing with
the SCO stuff. :-)
I'm just curious so I thought I'd ask.
