Problems sending UDP with CCL

Question

when I try to send a message as follow:

(let* ((temp-buffer message)
 (out-vector (make-array (length temp-buffer) 
             :element-type'(unsigned-byte 8)
             :initial-contents temp-buffer))
 (s (ccl:make-socket :remote-host host :remote-port port :type :datagram )))
(ccl:send-to s out-vector (length out-vector))
(ccl::close s))

I get the following error:

on #<CCL::UDP-SOCKET #x302000D9FCFD> : 
Socket is already connected (error #56) during sendto

Initially, this code was effective. Could anyone explain this error message and how to solve it. Thanks for any help.

You could try to post the question on the CCL developer list: [https://lists.clozure.com/mailman/listinfo/openmcl-devel](https://lists.clozure.com/mailman/listinfo/openmcl-devel). — Renzo, Apr 24 '16 at 10:07

This seems to work.

(let* ((temp-buffer message)
       (out-vector (make-array (length temp-buffer)
                               :element-type'(unsigned-byte 8)
                               :initial-contents temp-buffer))
       (s (ccl:make-socket :type :datagram)))
  (ccl:send-to s out-vector (length out-vector) :remote-host host :remote-port port)
  (ccl::close s))
