mq_close(3)
NAME
  mq_close - Closes a message queue  (P1003.1b)

SYNOPSIS
  #include <mqueue.h>

  int mq_close (
  mqd_t mqdes);

PARAMETERS
  mqdes	  Specifies a message queue descriptor.

DESCRIPTION
  Closes a message queue.  This function removes the association between the
  message queue descriptor, mqdes, and its open message queue description.
  When all message queue descriptors associated with an open message queue
  description have been closed, the associated open message queue description
  is removed.  The message associated with the message queue will then be
  deleted if mq_unlink was already called, or is called after all processes
  have closed the queue.

RETURN VALUES
  On successful completion, the function returns the value 0; otherwise, the
  function returns the value -1 and sets errno to indicate the error.

ERRORS
  The mq_close function fails under the following conditions:

  [EBADF]	 The mqdes argument is an invalid message queue descriptor.

  [EFAULT]	 Internal virtual memory error.
