If it returns false, then error will be set and the return values (**'d
stuff) will be unset.

The specification documents all of the methods on each interface:
 http://telepathy.freedesktop.org/spec.html

Almost all of the API of libtelepathy is just the result of running the
glib client bindings over those interfaces, so has no more documentation
than the spec itself. The header files and/or folklore and/or me can
tell you what the glib bindings turn certain D-Bus types into. There are
a couple of bits (tp_conn_new, tp_chan_new, and tp_conn_new_channel)
which set up stuff for you so you get objects and can pull out
ready-made proxies for the interfaces on the channels/connections, but
thats all pretty straightforward.

If you look at dbus.c from telepathy-feed, the last two methods show how
you can enumerate the existing connections on the bus. You can do that
and then find all of those which belong to the right manager and are for
the correct protocol, then get a handle for your account on that
connection, and see if it matches that connection's self handle. Then
you can reuse existing connections (even ones you did not create) which
match the account you were hoping to sign on.
