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-space programs should call the appropriate functions
by their usual names. Only standard library implementors and
kernel hackers need to know about ipc().
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.
