i was taking my first look at POSIX message queues, and have a
couple questions. first, it's easy enough to see if my current kernel
has mqueue support:
$ cat /proc/filesystems
...
nodev mqueue
...
and i'm assuming that that support is what automatically generates
the accompanying system directories /proc/sys/fs/mqueue/ and
/var/spool/mqueue/.
but, IIRC, you still can't actually use mqueues until you mount the
mqueue filesystem with some variation of:
# mkdir /dev/mqueue
# mount -t mqueue none /dev/mqueue
or at some other location, is this correct? and does it matter where
i mount that mqueue filesystem? will the mqueue kernel code
autodetect where i mounted it, even it it's in a non-standard
location? thanks.
