mq_unlink —
#include <mqueue.h>
int
  
  mq_unlink(const
    char *name);
mq_unlink() function removes the message queue named
  by the pathname name. After a successful call to
  mq_unlink() with name, a call to
  mq_open(3) with
  name fails if the flag O_CREAT
  is not set in flags. If one or more processes have the
  message queue open when mq_unlink() is called,
  destruction of the message queue will be postponed until all references to the
  message queue have been closed.
Calls to mq_open(3)
    to recreate the message queue may fail until the message queue is actually
    removed. However, the mq_unlink() call need not
    block until all references have been closed; it may return immediately.
mq_unlink() function fails if:
EACCES]ENAMETOOLONG]PATH_MAX}
      or a pathname component is longer than
    {NAME_MAX}.ENOENT]mq_unlink() function first appeared in
  NetBSD 5.0.
