        Can someone help me out this?

You'll want to use Glib::DBus::Proxy::create_for_bus_sync() (the async version is fine too)

https://developer.gnome.org/glibmm/2.34/classGio_1_1DBus_1_1Proxy.html#a275770db372ac7becfea4bb5fc2e9154

Then use proxy->call() or call_sync(). I guess you need a tuple variant with two strings, and you'll get a variant with just the cookie in it back.

Glib::Variant<Glib::ustring> app_name = Glib::Variant<Glib::ustring>::create("MyApp");

Glib::Variant<Glib::ustring> reason = Glib::Variant<Glib::ustring>::create("Playing movie");

std::vector<Glib::VariantBase> vec; 

vec.push_back(app_name);

vec.push_back(reason);

Glib::VariantContainerBase bundle = Glib::VariantContainerBase::create_tuple(vec);

Glib::VariantContainerBase result = proxy->call_sync(..., bundle, ...);

Glib::VariantBase child = result.get_child(0);

Glib::Variant<unsigned int> cookie;

try {

cookie = Glib::Variant<unsigned int>::cast_dynamic(child);

} catch (std::bad_cast e) {}

Although there's probably no reason to take apart the result, since for the UnInhibit you'll just shove 'result' right back into proxy->call_sync().

I have a class that uses the dbus notification interface here:
