Hi Jon,

Sorry, my previous answer was wrong. For an active FTP conn, given the fact
that the socket is created by the 'accept' call, curl does not call the
open/close-socket or sockopt callbacks.

Maybe we can think about an informative callback -- set with a new option
CURL_ACCEPTSOCKETFUNCTION to inform application if 'accept' creates a
socket for the data connection?

It looks to be a good idea.


What do you think about it?
