ipc — System V IPC system calls
int
ipc( |
unsigned int call, |
| int first, | |
| int second, | |
| int third, | |
| void *ptr, | |
long fifth); |
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 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.
msgctl(2), msgget(2), msgrcv(2), msgsnd(2), semctl(2), semget(2), semop(2), semtimedop(2), shmat(2), shmctl(2), shmdt(2), shmget(2)
