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 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

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