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 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 a few architectures, for example ia64, 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         top

       msgctl(2), msgget(2), msgrcv(2), msgsnd(2), semctl(2), semget(2), semop(2),
       semtimedop(2), shmat(2), shmctl(2), shmdt(2), shmget(2)
