Cred ca ar fi bine ca inainte de a posta un mesaj de genul sa se
citeasca documentatia.
[1] "The msg_len argument specifies the size of the buffer pointed to
by msg_ptr; this must be greater than the mq_msgsize attribute of the
queue (see mq_getattr(3)). If prio is not NULL, then the buffer to
which it points is used to return the priority associated with the
received message. "
