D-Bus list name

Question

How can I list all names in the D-Bus sessionBus with C?

I'm looking for the C GIO equivalent for the dbus.list_names python method

I want to list all names in «org.mpris.MediaPlayer2» which as example could be «org.mpris.MediaPlayer2.clementine, org.mpris.MediaPlayer2.someotherplayer, ...»

There is an application called «qdbusviewer» which does something similar

Answer 1

There is no specific GIO method for this tasks,

Bus names can be listet with a call to the «org.freedesktop.DBus.ListNames», filtering has to be done later.

Obtaining informations about the bus can be done with the introspection methods.

Answer 2

Information about the interface names, methods and arguments should be in the introspection section.

You can request information about an interface (e.g. org.mpris.MediaPlayer2) using the g_dbus_node_info_lookup_interface () method, to which you can give a GDBusNodeInfo argument, which should contain the path of the dbus object you want to query.

From this call you can get back a GDBusInterfaceInfo object which contains information about the methods and arguments of the requested interface.
