IPC(2)

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  argu-
       ments 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.
