NAME

6       ipc - System V IPC system calls
7

SYNOPSIS

9       int ipc(unsigned int call, int first, int second, int third,
10               void *ptr, long fifth);
11

DESCRIPTION

13       ipc()  is  a  common  kernel entry point for the System V IPC calls for
14       messages, semaphores, and shared memory.   call  determines  which  IPC
15       function  to  invoke;  the  other  arguments  are passed through to the
16       appropriate call.
17
18       User programs should call the  appropriate  functions  by  their  usual
19       names.   Only  standard library implementors and kernel hackers need to
20       know about ipc().
21

CONFORMING TO

23       ipc() is Linux-specific, and should not be used in programs intended to
24       be portable.
25

NOTES

27       On some architectures—for example x86-64 and ARM—there is no ipc() sys‐
28       tem call; instead msgctl(2), semctl(2), shmctl(2), and so on really are
29       implemented as separate system calls.
