TBH, attach sounds like I could call it multiple times to add several
"attachments". It's similar to "add". What about a simple zmq_msg_set_data()
or zmq_msg_set_buffer() ?

Or just to have one function(zmq_msg_create or zmq_msg_init) with 3
different signatures:

zmq_msg_create(zmq_msg_t *msg); // zmq_msg_init();
zmq_msg_create(zmq_msg_t *msg, size_t size); //  zmq_msg_init_size();
zmq_msg_create(zmq_msg_t *msg, size_t size, void *data, zmq_free_fn *ffn,
void *hint);

This way it would be much more clear that those functions are mutually
exclusive.
