ipc – System V IPC system calls

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 x86-64 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)
