Hello zimoun,

Well, I am confused by: > > (let ((content-ptr (zmq_msg_data (message->pointer message))) > [...] > (pointer->bytevector content-ptr size)))) > > … > > (let ((msg (pointer->message! msg-pointer))) > (when content-bv > (let ((target (zmq-message-content msg))) > (bytevector-copy! content-bv 0 target 0 len))) > msg)))) > > Is ’target’ at the same address than ’msg’? Maybe ’target’ creates > somehow a dangling pointer. No 'target' is not at the same address than 'msg', it's just a field of 'msg' that is allocated internally when "zmq_msg_init_size" is called. Allocating a message with "zmq_msg_init_size" and filling its content by memcpy'ing data to the memory region pointed by "zmq_msg_data" is the example given in "Man 3 zmq_msg_send", to I hope this is a valid use-case :). Thanks, Mathieu
