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, <A HREF="/man2/msgctl">msgctl(2)</A>, <A HREF="/man2/semctl">semctl(2)</A>, <A HREF="/man2/shmctl">shmctl(2)</A>, and so on really are implemented as separate system calls.
