## Details

### TrackerReplyArray ()

    void                (*TrackerReplyArray)                (gchar **result,
                                                             GError *error,
                                                             gpointer user_data);

### Warning

`TrackerReplyArray` has been deprecated since version 0.8 and should not be used in newly-written code. Use TrackerReplyVoid and TrackerReplyGPtrArray with `tracker_resources_sparql_query()` instead.

This is used by the 0.6 Tracker APIs: `tracker_search_metadata_by_text_async()` `tracker_search_metadata_by_text_and_location_async()` `tracker_search_metadata_by_text_and_mime_async()` `tracker_search_metadata_by_text_and_mime_and_location_async()`

`result` : | a gchar ** with the results of the query.
`error` : | a GError.
`user_data` : | a gpointer for user data.

### tracker_connect ()

    TrackerClient *     tracker_connect                     (gboolean enable_warnings,
                                                             gint timeout);

### Warning

`tracker_connect` has been deprecated since version 0.8 and should not be used in newly-written code. Use `tracker_client_new()` instead.

This function calls `tracker_client_new()`.

`enable_warnings` : | a gboolean to determine if warnings are issued in cases where they are found.
`timeout` : | a gint used for D-Bus call timeouts.
Returns : | a TrackerClient GObject which must be freed with `g_object_unref()`.

### tracker_disconnect ()

    void                tracker_disconnect                  (TrackerClient *client);

### Warning

`tracker_disconnect` has been deprecated since version 0.8 and should not be used in newly-written code. Use `g_object_unref()` instead.

This will disconnect the D-Bus connections to Tracker services and free the allocated TrackerClient by `tracker_connect()`.

`client` : | a TrackerClient.

### tracker_search_metadata_by_text_async ()

    guint               tracker_search_metadata_by_text_async
                                                            (TrackerClient *client,
                                                             const gchar *query,
                                                             TrackerReplyArray callback,

### Warning

`tracker_search_metadata_by_text_async` has been deprecated since version 0.8 and should not be used in newly-written code. Use `tracker_resources_sparql_query()` instead.

Searches for `query` in all URIs with the prefix `location`.

NOTE: `query` is found using FTS (Full Text Search).

`client` : | a TrackerClient.
`query` : | a string representing what to search for.
`callback` : | callback function to be called when the update has been processed.
`user_data` : | user data to pass to `callback`.
Returns : | A guint representing the operation ID. See `tracker_cancel_call()`. In the event of failure, 0 is returned.

### tracker_search_metadata_by_text_and_location_async ()

    guint               tracker_search_metadata_by_text_and_location_async
                                                            (TrackerClient *client,

### Warning

`tracker_search_metadata_by_text_and_location_async` has been deprecated since version 0.8 and should not be used in newly-written code. Use `tracker_resources_sparql_query()` instead.
