ipc(2) - Linux man page
Name
ipc - System V IPC system calls
Synopsis
int ipc(unsigned int call, int first, int secondint " 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.
