You're talking to Mr. Non-C coder, remember? So no, I couldn't do
But it should be pretty simple, no? Init the callbacks to NULL
automatically, and if they're NULL, then don't call them. (It
appears to call them both right away when you set the CURLOPT_SHARE
option for the easy handle, as well as later when you actually use
the handle for a transfer.)
For now, I'll just use my two dummy callbacks....
