ipc − System V IPC system calls

, int int ipc(unsigned int call , void *int third

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