- 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.
