Real-time library (librt, -lrt)
#include <mqueue.h>
int mq_unlink(const char *name);

queue name is removed immediately. The queue itself is destroyed
once any other processes that have the queue open close their
descriptors referring to the queue.
On success mq_unlink() returns 0; on error, -1 is returned, with
errno set to indicate the error.
EACCES The caller does not have permission to unlink this message
queue.
