The ANSI/ISO C standards don't mention "shared memory". However, assuming
that you have some (non-standard) way to obtain shared memory:

One issue is whether you can (and want to) make the shared memory appear
at the same address in all processes. If you cant, then you can't share
pointers between the processes, so you need to use e.g. indices or offsets
instead.

Also, you'll probably need some way to allocate blocks of memory from
within the shared region.
