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)
