NAME

       zmq_msg_copy - copy content of a message to another message

SYNOPSIS

       int zmq_msg_copy (zmq_msg_t *dest, zmq_msg_t *src);

DESCRIPTION

       The zmq_msg_copy() function shall copy the message object referenced by
       src to the message object referenced by dest. The original content of
       dest, if any, shall be released.

           Caution
           The implementation may choose not to physically copy the message
           content, rather to share the underlying buffer between src and
           dest. Avoid modifying message content after a message has been
           copied with zmq_msg_copy(), doing so can result in undefined
           behaviour. If what you need is an actual hard copy, allocate a new
           message using zmq_msg_init_size() and copy the message content
           using memcpy().

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

RETURN VALUE

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

ERRORS

       No errors are defined.
