shmget

See the current Perl documentation for shmget.

Here is our local, out-dated (pre-5.6) version:


shmget - get SysV shared memory segment identifier



shmget KEY,SIZE,FLAGS



Calls the System V IPC function shmget. Returns the shared memory segment id, or the undefined value if there is an error. See also IPC::SysV documentation.
