Hiya,
Nokia, being the Kings of Open Source that they are, won't release the
headers for libconnui - the library used by the Phone Control Panel
applet to perform this stuff.
However, libconnui is a wrapper around DBus-GLib/Mission Control etc.
Graham Cobb produced a brilliant Wiki page on working out the D-Bus
method calls:
https://garage.maemo.org/plugins/wiki/index.php?Tools&id=1106&type=g
I've attached three DBus-GLib examples which I believe should be
enough for you to perform what you asked for. I'm not sure what all
the values represent so... maybe looking at
www.bleb.org/software/maemo/telephony-maemo.c and
http://repository.maemo.org/extras-devel/pool/fremantle/free/source/n/netmon/
will help.
One will print a list of the available networks around you; this is
done in the way the CPA does it.
One will tell you the current Network Selection mode
(Manual/Automatic); the current cell information; and operator name.
The other will set the mode into automatic or manual (hardcoded for my
provider, T-Mobile UK).
Best regards,
Faheem
