NAME

       mq_unlink - remove a message queue

SYNOPSIS

       cc [ flag... ] file... -lrt [ library... ]
       #include <mqueue.h>

       int mq_unlink(const char *name);

       The  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(3RT) 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 is postponed until all references to the message queue have been closed. Calls to mq_open(3RT)
       to re-create 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.

       Upon  successful  completion,  mq_unlink() returns 0; otherwise, the named message queue is not changed by this function call, the function
       returns -1 and sets errno to indicate the error.

       The  mq_unlink() function will fail if:

       EACCES		       Permission is denied to unlink the named message queue.

       ENAMETOOLONG	       The length of the name  string  exceeds	 PATH_MAX,  or	a  pathname  component	is  longer  than   NAME_MAX  while
			       _POSIX_NO_TRUNC is in effect.

       ENOENT		       The named message queue, name, does not exist.

       ENOSYS		       mq_unlink() is not supported by the system.

       Solaris 2.6 was the first release to support the Asynchronous Input and Output option. Prior to this release, this function always returned
       -1 and set errno to ENOSYS.
