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
EFAULT Invalid message.
