NAME
ipc - System V IPC system calls
SYNOPSIS
int ipc(unsigned int call, int first, unsigned long second,
unsigned long third, void *ptr, long fifth);
Note:
There is no glibc wrapper for this system call; see NOTES.
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-space 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 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.
Glibc does not provide a wrapper for this system call;
in the unlikely event that you want to call it directly, you can do so using
syscall(2).
