System V IPC

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.
