[comp.os.mach] Using fork

artg@arnor.uucp (11/20/90)

I`m running mach 2.5 on IBM RTs.  Since task_create() doesnt
exist for this system we use fork.  There are two
implmentations of it, fork() and unix_fork().  How do the 
semantics of these two operations differ?

My overall objective, is to duplicate the address space, so one
task can checkpoint a snapshot of the address space while another
keeps on doing useful work.
thanks
