NAME
       dat_cno_free - destroy an instance of the CNO

SYNOPSIS
       cc [ flag... ] file... -ldat [ library... ]
       #include <dat/udat.h>

       DAT_RETURN
	   dat_cno_free (
	   IN	 DAT_CNO_HANDLE	   cno_handle
	   )

PARAMETERS
       cno_handle      Handle for an instance of the CNO

DESCRIPTION
       The dat_cno_free() function destroys a specified instance of the CNO.

       A  CNO  cannot be deleted while it is referenced by an Event Dispatcher
       or while a thread is blocked on it.

RETURN VALUES
       DAT_SUCCESS	       The operation was successful.

       DAT_INVALID_HANDLE      The cno_handle() parameter is invalid.

       DAT_INVALID_STATE       Parameter in an invalid state. CNO is in use by
			       an EVD instance or there is a thread blocked on
			       it.

USAGE
       If there is a thread blocked in dat_cno_wait(3DAT), the Consumer can do
       the following steps to unblock the waiter:

	 ·  Create  a  temporary  EVD  that accepts software events. It can be
	    created in advance.

	 ·  For a CNO with the waiter, attach that EVD to the CNO and post the
	    software event on the EVD.

	 ·  This unblocks the CNO.

	 ·  Repeat for other CNOs that have blocked waiters.

	 ·  Destroy the temporary EVD after all CNOs are destroyed and the EVD
	    is no longer needed.
