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. + + +SEE ALSO +-------- +linkzmq:zmq_msg_move[3] +linkzmq:zmq_msg_init[3] +linkzmq:zmq_msg_init_size[3] +linkzmq:zmq_msg_init_data[3] +linkzmq:zmq_msg_close[3] +linkzmq:zmq[7] + + +AUTHORS +------- +This page was written by the 0MQ community.
