You've got "abstract" void* pointer attached to every libssh2 to pass
any context to your handler (use libssh2_session_abstract to access it):

static void
MyCplusPlusWrapper::keyboardinteractive_handler(
        const char* name,
        int name_len, ...,
        void* abstract)
{
  MyCplusPlusWrapper* this_ = static_cast<MyCplusPlusWrapper*>(abstract);

  this_-> ....
}

This is pretty common pattern in C world, I'm pretty sure you've seen it
numerous times under the "ctx" or "context" name.

It's impossible. Have a look at the protocol specification.
