IPC(2)                    Linux Programmer's Manual                   IPC(2)

NAME         top

       ipc - System V IPC system calls

SYNOPSIS         top

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

DESCRIPTION         top

       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().

CONFORMING TO         top

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

NOTES         top

       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.

       semop(2), semtimedop(2), shmat(2), shmctl(2), shmdt(2), shmget(2),
