NAME

       ipc_init - initialise IPC subsystem

SYNOPSIS

       int ipc_init(void);

ARGUMENTS

       void
	   no arguments

DESCRIPTION

       The various system5 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.

NAME

       ipc - System V IPC system calls

SYNOPSIS

       int ipc(unsigned int call, int first, int second, int third,
	       void *ptr, long fifth);

DESCRIPTION

       ipc()  is  a  common  kernel entry point for the System V IPC calls for messages, semaphores, and shared memory.  call determines which IPC
       function to invoke; the other arguments are passed through to the appropriate call.

       User programs should call the appropriate functions by their usual names.  Only standard library implementors and kernel  hackers  need	to
       know about ipc().

CONFORMING TO

       ipc() is Linux-specific, and should not be used in programs intended to be portable.

NOTES

       On  a  few  architectures,  for	example ia64, there is no ipc() system call; instead msgctl(2), semctl(2), shmctl(2), and so on really are
       implemented as separate system calls.
