- System V IPC
- CONFIG_SYSVIPC
- Inter Process Communication is a suite of library functions and
- system calls which let processes (running programs) synchronize and
- exchange information. It is generally considered to be a good thing,
- and some programs won't run unless you say Y here. In particular, if
- you want to run the DOS emulator dosemu under Linux (read the
- DOSEMU-HOWTO, available from
- http://www.linuxdoc.org/docs.html#howto ), you'll need to say Y
- here.

- You can find documentation about IPC with "info ipc" and also in
- section 6.4 of the Linux Programmer's Guide, available from
- http://www.linuxdoc.org/docs.html#guide .

- Shared memory is now implemented using a new (minimal) virtual file
- system, which you need to mount before programs can use shared memory.
- To do this automatically at system startup just add the following line
- to your /etc/fstab:
-
- none /var/shm shm defaults 0 0
-
- Saying Y here enlarges your kernel by about 18 KB. Just say Y.
