Subject: [PATCH 2/3] Various pages: Remove unused <sys/ipc.h> (and <sys/types.h>)
Date: Thu, 22 Apr 2021 00:44:18 +0200 [thread overview]
Message-ID: <20210421224418.143065-2-alx.manpages@gmail.com> (raw)
In-Reply-To: <20210421224418.143065-1-alx.manpages@gmail.com>
In b0b19983d9a2001ce94b908a99f4c05a50fd47ee we removed
<sys/types.h>. For the same reasons there, remove now <sys/ipc.h>
from many pages.
If someone wonders why <sys/ipc.h> was needed, the reason was to
get all the definitions of IPC_* constants. However, that header
is now included by <sys/msg.h>, so it's not needed anymore to
explicitly include it. Quoting POSIX: "In addition, the
<sys/msg.h> header shall include the <sys/ipc.h> header."
There were some remaining cases where I forgot to remove
<sys/types.h>; remove them now too.
