POSIX message queues folder

I've been working remotely with POSIX message queues for some days. Now I want to do it in my own PC but I've found that there's no /dev/mqueue folders where queues are created; which means that I don't know where they are (of whether there are or not), so I can't access there to delete them in case of an unexpected end of my program.

I notice my code is not running properly due to 'zombie' queues, but I can't remove them from that folder as I do with semaphores and shared memories (hosted in /dev/shm).

I suspect that some configuration about this can be done with the following command, but I'd like to be aware of what I am doing before changing anything.

mount -t mqueue none /dev/mqueue

I hope I've managed to show you my problem, so that someone can give me a solution.

Thanks in advance,

Eduardo
