Possix queue names

I am facing a problem while using mq_open
For a queue named "/queue" i get an error
"Not enough memory" while for other name like "/Core_1_queue" it works ok.
Can someone explain what is going on ?
What is the exact convention for queue names ?
Thanks

I suspect that this is not a queue name problem.

If you check out the manual (http://man7.org/linux/man-pages/man3/mq_open.3.html) you should have received an EACCES, EINVAL, ENAMETOOLONG or ENOENT error if there was a problem with the name.

That manual page points to http://man7.org/linux/man-pages/man7/mq_overview.7.html which describes that the queue name should be:

Quote:

a null-terminated string of up to NAME_MAX (i.e., 255) characters consisting of an initial slash, followed by one or more characters, none of which are slashes.

However, you are receiving an out-of-memory error (ENOMEM?). You need first to determine which error number is being returned.

Perhaps the problem is something along the lines of this one: http://stackoverflow.com/questions/5...ge-queue-in-po.
