ipc(2) System Calls Manual ipc(2)
ipc - System V IPC system calls
Standard C library (libc, -lc)
#include <linux/ipc.h> /* Definition of needed constants */
#include <sys/syscall.h> /* Definition of SYS_* constants */
#include <unistd.h>
int syscall(SYS_ipc, unsigned int call, int first,
unsigned long second, unsigned long third, void *ptr,
long fifth);
Note: glibc provides no wrapper for ipc(), necessitating the use
of syscall(2).
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-space programs should call the appropriate functions by
their usual names. Only standard library implementors and kernel
hackers need to know about ipc().
On some architectures—for example x86-64 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.
