[libvirt] Some questions about virConnectAuthCallbackPtr

Some questions which seem to be left ambigious by the documentation for virConnectAuthCallbackPtr: http://libvirt.org/html/libvirt-libvirt.html#virConnectAuthCallbackPtr (1) For a single open, can this be called multiple times? I'm thinking, some authentication methods might give the user N attempts at typing the password, which might result in N callbacks here. (2) The documentation says: "Returns: 0 if all interactions were filled, or -1 upon error". However it also says "If an interaction cannot be filled, fill in NULL and 0". Does that mean it's OK (not an error, return 0) if a result field is set to NULL?
