MQ_CLOSE(2)		    BSD System Calls Manual		   MQ_CLOSE(2)

NAME
     mq_close — close a message queue (REALTIME)

LIBRARY
     POSIX Real-time Library (librt, -lrt)

SYNOPSIS
     #include <mqueue.h>

     int
     mq_close(mqd_t mqdes);

DESCRIPTION
     The mq_close() system call removes the association between the message
     queue descriptor, mqdes, and its message queue.  The results of using
     this message queue descriptor after successful return from this
     mq_close(), and until the return of this message queue descriptor from a
     subsequent mq_open(), are undefined.

     If the process has successfully attached a notification request to the
     message queue via this mqdes, this attachment will be removed, and the
     message queue is available for another process to attach for notifica‐
     tion.

RETURN VALUES
     Upon successful completion, the value 0 is returned; otherwise the
     value -1 is returned and the global variable errno is set to indicate the
     error.

ERRORS
     The mq_close() system call will fail if:

     [EBADF]		The mqdes argument is not a valid message queue
			descriptor.

SEE ALSO
     mq_open(2), mq_unlink(2)

STANDARDS
     The mq_close() system call conforms to IEEE Std 1003.1-2004 (“POSIX.1”).

HISTORY
     Support for POSIX message queues first appeared in FreeBSD 7.0.
