RE: Newbie: how to talk to NM by C or C++? Need some hints.

["Andy Maginnis" <jam smru co uk>]

Also try experimenting with qdbus & dbus-send, these are really helping me
find my way around. If you can get the dbus-send to work you should be
able to transfer this to c/perl/python easily

Some examples below:
qdbus --system org.freedesktop.NetworkManager /org/freedesktop/NetworkManager
dbus-send --system --print-reply --dest="org.freedesktop.NetworkManager" /org/freedesktop/NetworkManagerSettings "org.freedesktop.NetworkManagerSettings.ListConnections"

Sorry for stating the obvious but... first you need to be familiar
with D-Bus, did you realize that?

For such tasks you might spend less time parsing the output of
"nmcli" or "cnetworkmanager". Especially if your code is just an
"experiment".
