Re: [Boost-users] ipc message_queue getting permission denied

The code as is, the /tmp/boost_interprocess is not created, which made
me wonder if the shared memory handle is trying to be made somewhere
else.  If I call boost::iterprocess::detail::create_tmp_and_clean_old,
it creates /tmp/boost_interprocess with 777 permissions.  However even
if this folder is created with the correct write access, I still get
Permission denied when not root user.  Which brings me back to my
theory that something else is going on with the shared memory handle
that it isn't being created in /tmp/boost_interprocess.  Also to note,
my /tmp dir is also 777.
Thanks,
Matt
