## Description

Some connection manager implementations can be instructed to try to save power on mobile devices by suppressing non-essential traffic, such as presence notifications. This section documents auto-generated C wrappers for the PowerSaving D-Bus interface.

### tp_cli_connection_interface_power_saving_call_set_power_saving ()

    TpProxyPendingCall *
    tp_cli_connection_interface_power_saving_call_set_power_saving
                                   (TpConnection *proxy,
                                    gint timeout_ms,
                                    gboolean in_Activate,
                                    tp_cli_connection_interface_power_saving_callback_for_set_power_saving callback,
                                    gpointer user_data,
                                    GDestroyNotify destroy,
                                    GObject *weak_object);

Start a SetPowerSaving method call.

<tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>Turn power saving mode on or off.</p> <tp:rationale> <p>Depending on the device's activity level, the connection can have its power saving mode turned on or off.</p> </tp:rationale> <p>Errors raised by this method indicate that power saving could not be enabled, which SHOULD NOT generally be treated as fatal.</p> <tp:rationale> If the CM cannot switch modes, either because of the protocol (<code>NotImplemented</code>), or because of the service (<code>NotAvailable</code>), Mission Control (or whoever manages this) should be made aware. The error could be ignored or, in the extreme, be fascist and disconnect the account. </tp:rationale>

#### Parameters

proxy | the TpProxy |
timeout_ms | the timeout in milliseconds, or -1 to use the default |
in_Activate | Used to pass an 'in' argument: <code>True</code> if protocol-level power saving features should be activated; <code>False</code> if they should be de-activated. |
callback | called when the method call succeeds or fails; may be `NULL` to make a "fire and forget" call with no reply tracking |
user_data | user-supplied data passed to the callback; must be `NULL` if `callback` is `NULL` |
destroy | called with the user_data as argument, after the call has succeeded, failed or been cancelled; must be `NULL` if `callback` is `NULL` |
weak_object | If not `NULL`, a GObject which will be weakly referenced; if it is destroyed, this call will automatically be cancelled. Must be `NULL` if `callback` is `NULL` |

#### Returns

a TpProxyPendingCall representing the call in progress. It is borrowed from the object, and will become invalid when the callback is called, the call is cancelled or the TpProxy becomes invalid.

### tp_cli_connection_interface_power_saving_callback_for_set_power_saving ()

    void
    (*tp_cli_connection_interface_power_saving_callback_for_set_power_saving)
                                   (TpConnection *proxy,
                                    const GError *error,
                                    gpointer user_data,
                                    GObject *weak_object);

Signature of the callback called when a SetPowerSaving method call succeeds or fails.

#### Parameters

proxy | the proxy on which the call was made |
error | `NULL` on success, or an error on failure |
user_data | user-supplied data |
weak_object | user-supplied object |

### tp_cli_connection_interface_power_saving_connect_to_power_saving_changed ()

    TpProxySignalConnection *
    tp_cli_connection_interface_power_saving_connect_to_power_saving_changed
                                   (TpConnection *proxy,
                                    tp_cli_connection_interface_power_saving_signal_callback_power_saving_changed callback,
                                    gpointer user_data,
                                    GDestroyNotify destroy,
                                    GObject *weak_object,
                                    GError **error);

Connect a handler to the signal PowerSavingChanged.

<tp:docstring xmlns="http://www.w3.org/1999/xhtml"> The <tp:member-ref>PowerSavingActive</tp:member-ref> property changed.

#### Parameters

proxy | A TpConnection or subclass |
callback | Callback to be called when the signal is received |
user_data | User-supplied data for the callback |
destroy | Destructor for the user-supplied data, which will be called when this signal is disconnected, or before this function returns `NULL` |
weak_object | A GObject which will be weakly referenced; if it is destroyed, this callback will automatically be disconnected |
error | If not `NULL`, used to raise an error if `NULL` is returned |

#### Returns

a TpProxySignalConnection containing all of the above, which can be used to disconnect the signal; or `NULL` if the proxy does not have the desired interface or has become invalid.

### tp_cli_connection_interface_power_saving_signal_callback_power_saving_changed ()

    void
    (*tp_cli_connection_interface_power_saving_signal_callback_power_saving_changed)
                                   (TpConnection *proxy,
                                    gboolean arg_Active,
                                    gpointer user_data,
                                    GObject *weak_object);

Represents the signature of a callback for the signal PowerSavingChanged.

#### Parameters

proxy | The proxy on which `tp_cli_connection_interface_power_saving_connect_to_power_saving_changed()` was called |
arg_Active | The new state of the power saving feature. |
user_data | User-supplied data |
weak_object | User-supplied weakly referenced object |
