NAME

       ipc_addid - add an IPC identifier

SYNOPSIS

       int ipc_addid(struct ipc_ids * ids, struct kern_ipc_perm * new, int size);

ARGUMENTS

       ids
	   IPC identifier set

       new
	   new IPC permission set

       size
	   limit for the number of used ids

DESCRIPTION

       Add an entry 'new' to the IPC ids idr. The permissions object is initialised and the first free entry is set up and the id assigned is
       returned. The 'new' entry is returned in a locked state on success. On failure the entry is not locked and a negative err-code is returned.

       Called with writer ipc_ids.rwsem held.

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 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.
