ZMQ_MSG_CLOSE(3)		  0MQ Manual		      ZMQ_MSG_CLOSE(3)

NAME
       zmq_msg_close - release 0MQ message

SYNOPSIS
       int zmq_msg_close (zmq_msg_t *msg);

DESCRIPTION
       The zmq_msg_close() function shall inform the 0MQ infrastructure	that
       any resources associated	with the message object	referenced by msg are
       no longer required and may be released. Actual release of resources
       associated with the message object shall	be postponed by	0MQ until all
       users of	the message or underlying data buffer have indicated it	is no
       longer required.

       Applications should ensure that zmq_msg_close() is called once a
       message is no longer required, otherwise	memory leaks may occur.	Note
       that this is NOT	necessary after	a successful zmq_msg_send().

	   Caution

	   Never access	zmq_msg_t members directly, instead always use the
	   zmq_msg family of functions.

RETURN VALUE
       The zmq_msg_close() function shall return zero if successful. Otherwise
       it shall	return -1 and set errno	to one of the values defined below.

ERRORS
       EFAULT
	   Invalid message.
