NAME
       mq_unlink - unlink a message queue

SYNOPSIS
DESCRIPTION
       The  system  call  disassociates	 the  queue name, from a message queue
       specified by the argument, name.	 After a successful call  to  attempts
       to  open	 a  message queue with the same name will fail, if the flag is
       not set in oflags.

       If there are no processes with existing open descriptors for  the  mes‐
       sage  queue,  the queue is destroyed. If one or more processes have the
       message queue open, the removal of the queue  is	 postponed  until  all
       descriptors for the queue have been closed.

       To use this function, link in the realtime library by specifying on the
       compiler or linker command line.
