libssh2 - public key and/or password auth methods

How should an application determine whether both public key
and password authentication methods are required?
I'm not sure how to determine the difference between a server
that requires both, or will take either one.

I was kind of expecting functions like libssh2_userauth_publickey_fromfile
and libssh2_userauth_password to have a return code that says
"successful so far, but more authentication is required".

Thanks.
