Hi,

I wrote a small C++ program using libdbus-c++ to scan for access
points via wpa_supplicant's dbus interface.  It works very well, and I
can retrieve the list just fine.

Now I want to cause it to scan for a specific SSID by issuing a probe,
but the dbus interface fi.epitest.hostap.WPASupplicant.Interface has
only one scan method, and it does not seem to take arguments.
(Looking at the source file ctrl_iface_dbus_handlers.c in function
wpas_dbus_iface_scan() you can see why - it doesn't handle or even
look at the arguments to the message).

Is there another way to accomplish this?  I notice that a number of
dbus messages trigger a scan.  I don't really want to try to associate
with it, but perhaps that's the only way.

(I guess I could try to trigger the scan via netlink and receive the
results via dbus..... messy).
