ipc — System V IPC system calls

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