# ipc\_init(9)

initialise ipc subsystem

## NAME

ipc\_init - initialise ipc subsystem

## SYNOPSIS

**int ipc\_init(***void***);**

no arguments

## DESCRIPTION

The various sysv ipc resources (semaphores, messages and shared memory) are initialised.

A callback routine is registered into the memory hotplug notifier chain: since msgmni scales to lowmem this callback routine will be called upon successful memory add / remove to recompute msmgni.
