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.
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.
