used by a directory.

These calls are made on a best-effort basis and not all types of

always be made immediately.

In the case that there is no support, /@reporting@/ will be set to

Signature for function used in 'GI.Gio.Objects.DBusConnection.dBusConnectionAddFilter'.

A filter function is passed a 'GI.Gio.Objects.DBusMessage.DBusMessage' and expected to return
a 'GI.Gio.Objects.DBusMessage.DBusMessage' too. Passive filter functions that don\'t modify the
message can simply return the /@message@/ object:
>
>static GDBusMessage *
>passive_filter (GDBusConnection *connection
>                GDBusMessage    *message,
>                gboolean         incoming,
>                gpointer         user_data)
>{
>  // inspect @message
>  return message;
>}

Filter functions that wants to drop a message can simply return 'Nothing':
>
>static GDBusMessage *
>drop_filter (GDBusConnection *connection
>             GDBusMessage    *message,
>             gboolean         incoming,

>    {

>      message = NULL;

A filter function is passed a 'GI.Gio.Objects.DBusMessage.DBusMessage' and expected to return
a 'GI.Gio.Objects.DBusMessage.DBusMessage' too. Passive filter functions that don\'t modify the
message can simply return the /@message@/ object:
>
>static GDBusMessage *
>passive_filter (GDBusConnection *connection
>                GDBusMessage    *message,

>                gpointer         user_data)
>{
>  // inspect @message
>  return message;
>}

Filter functions that wants to drop a message can simply return 'Nothing':
>
>static GDBusMessage *
>drop_filter (GDBusConnection *connection
>             GDBusMessage    *message,
>             gboolean         incoming,
