IPC and shared memory implementations on *nix machines
[edit]There is one SysV IPC implementation and there are "two" POSIX IPC implementations. When referring to POSIX:
- The first "group" is POSIX:XSI IPC which appears to ratify the SysV functions (so to all intents this and purposes this is synonymous with talking about SysV IPC)
- The second "group" is the POSIX Realtime Option Group. Most of the functions in that group do radically different things to the above but POSIX Memory Mapped Files offer an alternative way to do shared memory via `shm_open()/mmap()/shm_unlink()`.
