dbus_set_g_error ()

void                dbus_set_g_error                    (GError **gerror,
                                                         DBusError *derror);

Store the information from a DBus method error return into a GError. For the normal case of an arbitrary remote process, the error code will be DBUS_GERROR_REMOTE_EXCEPTION. Now, DBus errors have two components; a message and a "name". The former is an arbitrary (normally American English) string. The second is a string like com.example.FooFailure which programs can use as a conditional source. Because a GError only has one string, we use a hack to encode both values:

<human readable string><null><error name><null>

You can use the following code to retrieve both values:

1
2
3

const char *msg = error->message;
size_t len = strlen(msg);
const char *error_name = msg+len+1;

dbus_connection_setup_with_g_main ()

void                dbus_connection_setup_with_g_main   (DBusConnection *connection,
                                                         GMainContext *context);

Sets the watch and timeout functions of a DBusConnection to integrate the connection with the GLib main loop. Pass in NULL for the GMainContext unless you're doing something specialized.

If called twice for the same context, does nothing the second time. If called once with context A and once with context B, context B replaces context A as the context monitoring the connection.

dbus_connection_get_g_connection ()

DBusGConnection *   dbus_connection_get_g_connection    (DBusConnection *connection);

Get the DBusGConnection corresponding to this DBusConnection. This only makes sense if the DBusConnection was originally a DBusGConnection that was registered with the GLib main loop. The return value does not have its refcount incremented.

dbus_server_setup_with_g_main ()

void                dbus_server_setup_with_g_main       (DBusServer *server,
                                                         GMainContext *context);

Sets the watch and timeout functions of a DBusServer to integrate the server with the GLib main loop. In most cases the context argument should be NULL.

If called twice for the same context, does nothing the second time. If called once with context A and once with context B, context B replaces context A as the context monitoring the connection.

DBUS_TYPE_CONNECTION

#define DBUS_TYPE_CONNECTION      (dbus_connection_get_g_type ())

Expands to a function call returning a boxed GType representing a DBusConnection pointer from libdbus. Not to be confused with DBUS_TYPE_G_CONNECTION, which you should usually use instead.

DBUS_TYPE_MESSAGE

#define DBUS_TYPE_MESSAGE         (dbus_message_get_g_type ())

Expands to a function call returning a boxed GType representing a DBusMessage pointer from libdbus. Not to be confused with DBUS_TYPE_G_MESSAGE, which you should usually use instead.
