void *ptr, long fifth);
ipc() is a common kernel entry point for the System V IPC calls for

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
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.
