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().
ipc() is Linux-specific, and should not be used in programs intended to be portable.
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.
