return value from sasl_client_start()

[Ted Yu]

w.r.t. callbacks :

  if (userid) {
    callback->id = SASL_CB_USER;
    callback->proc = (sasl_callback_ft)&simple;

Is SASL_CB_USER required ?

Earlier I sent out an email "Casting function pointers to sasl_callback_ft"
where I described issue casting my method to signature of proc member.

If someone has used the callbacks in C++11 environment, please share your
experience.
