IPC(2) Linux Programmer's Manual 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 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 some architectures--for example x86-46 and ARM--there is no ipc() system call; instead msgctl(2), semctl(2), shmctl(2), and so on really
are implemented as separate system calls.
SEE ALSO
msgctl(2), msgget(2), msgrcv(2), msgsnd(2), semctl(2), semget(2), semop(2), semtimedop(2), shmat(2), shmctl(2), shmdt(2), shmget(2)
COLOPHON
This page is part of release 3.44 of the Linux man-pages project. A description of the project, and information about reporting bugs, can
