Yes. It is called system V shared memory. mmap will also be able to
do that as well, if you use a backing file (is that still required?)

You are limited by the number of shared memory areas you can have, and
their size. You can have any number of pointers into this memory that
you want. You'll need to come up with some kind of wrapper for this
stuff as well. Also, there are no guarantees, iirc, that the shared
memory segment will be at the same virtual address in both processes,
so pointers in one program won't work in the other w/o a translation,
which can be, ahhhh, tricky.

Just use shm*. You will be much happier. Trust me.
