## Functions

### gclue_client_interface_info ()

    GDBusInterfaceInfo *
    gclue_client_interface_info (void);

Gets a machine-readable description of the org.freedesktop.GeoClue2.Client D-Bus interface.

#### Returns

A GDBusInterfaceInfo. Do not free.

                                    GError **error);

Finishes an operation started with `gclue_client_call_start()`.

#### Parameters

proxy | A GClueClientProxy. |
res | The GAsyncResult obtained from the GAsyncReadyCallback passed to `gclue_client_call_start()`. |

                                  GError **error);

Synchronously invokes the `Start()` D-Bus method on `proxy` . The calling thread is blocked until a reply is received.

See `gclue_client_call_start()` for the asynchronous version of this method.

#### Parameters

proxy | A GClueClientProxy. |

Flags: Read / Write

Default value: NULL

### The `“distance-threshold”` property

      “distance-threshold”       guint

## Signal Details

### The `“handle-start”` signal

    gboolean
    user_function (GClueClient           *object,
                   GDBusMethodInvocation *invocation,
                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `Start()` D-Bus method.

If a signal handler returns `TRUE`, it means the signal handler will handle the invocation (e.g. take a reference to `invocation` and eventually call `gclue_client_complete_start()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no order signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A GClueClient. |
invocation | A GDBusMethodInvocation. |
user_data | user data set when the signal handler was connected. |

#### Returns

`TRUE` if the invocation was handled, `FALSE` to let other signal handlers run.

Flags: Run Last

### The `“handle-stop”` signal

    gboolean
    user_function (GClueClient           *object,
                   GDBusMethodInvocation *invocation,
                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `Stop()` D-Bus method.

If a signal handler returns `TRUE`, it means the signal handler will handle the invocation (e.g. take a reference to `invocation` and eventually call `gclue_client_complete_stop()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no order signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A GClueClient. |
invocation | A GDBusMethodInvocation. |
user_data | user data set when the signal handler was connected. |

#### Returns

`TRUE` if the invocation was handled, `FALSE` to let other signal handlers run.

Flags: Run Last

### The `“location-updated”` signal

    void
    user_function (GClueClient *object,
                   gchar       *arg_old,
                   gchar       *arg_new,
                   gpointer     user_data)

On the client-side, this signal is emitted whenever the D-Bus signal "LocationUpdated" is received.

On the service-side, this signal can be used with e.g. `g_signal_emit_by_name()` to make the object emit the D-Bus signal.

#### Parameters

object | A GClueClient. |
arg_old | Argument. |
arg_new | Argument. |
user_data | user data set when the signal handler was connected. |

Flags: Run Last
