as a requirement for calling these functions.
That was my first thought, but according to
http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/sys_ipc.h.html
``The <sys/ipc.h> header shall define the uid_t, gid_t, mode_t and key_t
types as described in <sys/types.h>'', which is currently not the case.
Unfortunately it doesn't allow us to make everything in <sys/types.h>
available though. So simply including <sys/types.h> from <sys/ipc.h>
isn't the right solution.
No, it does permit us to just #include <sys/types.h>, because POSIX
reserves the *_t namespace in all its headers, and that's all that
<sys/types.h> exports. We've tried to do more minimal
#including/exporting generally, but SysV IPC is enough of a corner
that just pulling in <sys/types.h> from <sys/ipc.h> is fine by me.
ping. Discussion died out. Can we please move this issue forward?
