Hi, My apologies if this is a frequent question, I could not find an answer.
It would be convenient for me to retrieve the local address of the connected socket used for an HTTP GET before the HTTP transaction begins. The pseudo HTTP protocol which my code implements (UPnP) needs to set a HTTP header which contains a callback URL for the remote host to send events to. In case the local machine has multiple interfaces, the easiest way to build an URL which the remote is guaranteed to be able to connect to seems to be just using the connected socket local address. Unfortunately, it seems that the two callbacks in this area, CURLOPT_SOCKOPTFUNCTION and CURLOPT_OPENSOCKETFUNCTION, occur before the socket is connected. I could connect the socket myself (losing the nice CURL code which does it for me), or find another way to derive the right interface from the remote address I am connecting to, but a getsockname() on the connected socket would be much simpler. So I was hoping that there was a way. This is assuming that I can call CURLOPT_HTTPHEADER from this point, which may also not be the case. So, questions... Thanks for this nice library !
