SPUG: sysv shared memory and forking

Let's say I have a parent process that creates and attaches a pointer to a
shared memory segment and then forks off a number of children.  I
understand the children will inherit the parent's address space (copy on
write and all that) and thus the pointer attached to the shared memory
segment.  However, do they inherit the entire memory segment as well?  Or
is the sysv memory segment created outside the parent processes address
space to begin with?

Thanks,
--Ben
