NAME
ipc - System V IPC system calls
SYNOPSIS
int ipc(unsigned int call, int first, int second, int third,
void *ptr, long fifth);
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 programs should call the appropriate functions by their usual names.
Only standard library implementors and kernel hackers need to know about
ipc().
CONFORMING TO
ipc()
is Linux-specific, and should not be used in programs
intended to be portable.
NOTES
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.
