28 ipc \- System V IPC system calls

33 .BI " void *" ptr ", long " fifth );
37 is a common kernel entry point for the System V IPC calls
38 for messages, semaphores, and shared memory.
40 determines which IPC function to invoke;
41 the other arguments are passed through to the appropriate call.
43 User programs should call the appropriate functions by their usual names.
44 Only standard library implementors and kernel hackers need to know about
48 is Linux-specific, and should not be used in programs
49 intended to be portable.
51 On a few architectures, for example ia64, there is no
57 and so on really are implemented as separate system calls.
