Are your processes all created by fork() or are they unrelated? If they're
all descendants of the same process, take a look at the GNU mm library
(which is loosely based on structure of the mm_malloc library I wrote for my
company but couldn't release).

If they're unrelated, you'll have to use SysV.

Subject: shared memory models/techniques
hope this is an ok place to post this.
as far as i can tell there are three ways to share memory between processes
-
using mmap, ipc shared mem or skip it using threads instead.
is this right?
basically i have a server process accepting many connections & i was using
threads, however, it doesn't really make sense processes would probably be
simpler with shared mem. i was going to use IPC but don't like building
uncessesary dependancies (i.e. it's a kernel option).
is mmap the best way to do this? why would you use ipc instead?
. . . and finally (milking the assistance to the last) is there a really
simple app using shared mem resources that anyone knows about so i can
butcher
it?
thanks in advance.
