    GDBusInterfaceInfo * udisks_swapspace_interface_info    (void);

Gets a machine-readable description of the org.freedesktop.UDisks2.Swapspace D-Bus interface.

Returns : | A GDBusInterfaceInfo. Do not free. [transfer none]

### udisks_swapspace_override_properties ()

    guint               udisks_swapspace_override_properties

`klass` : | The class structure for a GObject-derived class.
`property_id_begin` : | The property id to assign to the first overridden property.
Returns : | The last property id.

### udisks_swapspace_call_start ()

    void                udisks_swapspace_call_start         (UDisksSwapspace *proxy,

Asynchronously invokes the `Start()` D-Bus method on `proxy`. When the operation is finished, `callback` will be invoked in the thread-default main loop of the thread you are calling this method from. You can then call `udisks_swapspace_call_start_finish()` to get the result of the operation.

See `udisks_swapspace_call_start_sync()` for the synchronous, blocking version of this method.

`proxy` : | A UDisksSwapspaceProxy.
`arg_options` : | Argument to pass with the method invocation.
`cancellable` : | A GCancellable or `NULL`. [allow-none]
`callback` : | A GAsyncReadyCallback to call when the request is satisfied or `NULL`.
`user_data` : | User data to pass to `callback`.

### udisks_swapspace_call_start_finish ()

    gboolean            udisks_swapspace_call_start_finish  (UDisksSwapspace *proxy,

Finishes an operation started with `udisks_swapspace_call_start()`.

`proxy` : | A UDisksSwapspaceProxy.
`res` : | The GAsyncResult obtained from the GAsyncReadyCallback passed to `udisks_swapspace_call_start()`.
`error` : | Return location for error or `NULL`.
Returns : | `TRUE` if the call succeded, `FALSE` if `error` is set. [skip]

### udisks_swapspace_call_start_sync ()

    gboolean            udisks_swapspace_call_start_sync    (UDisksSwapspace *proxy,
                                                             GVariant *arg_options,
                                                             GCancellable *cancellable,
                                                             GError **error);

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

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

`proxy` : | A UDisksSwapspaceProxy.
`arg_options` : | Argument to pass with the method invocation.
`cancellable` : | A GCancellable or `NULL`. [allow-none]
`error` : | Return location for error or `NULL`.
Returns : | `TRUE` if the call succeded, `FALSE` if `error` is set. [skip]

### udisks_swapspace_complete_start ()

    void                udisks_swapspace_complete_start     (UDisksSwapspace *object,
                                                             GDBusMethodInvocation *invocation);

Helper function used in service implementations to finish handling invocations of the `Start()` D-Bus method. If you instead want to finish handling an invocation by returning an error, use `g_dbus_method_invocation_return_error()` or similar.

This method will free `invocation`, you cannot use it afterwards.

`object` : | A UDisksSwapspace.
`invocation` : | A GDBusMethodInvocation. [transfer full]

### udisks_swapspace_call_stop ()

    void                udisks_swapspace_call_stop          (UDisksSwapspace *proxy,

Asynchronously invokes the `Stop()` D-Bus method on `proxy`. When the operation is finished, `callback` will be invoked in the thread-default main loop of the thread you are calling this method from. You can then call `udisks_swapspace_call_stop_finish()` to get the result of the operation.

See `udisks_swapspace_call_stop_sync()` for the synchronous, blocking version of this method.

`proxy` : | A UDisksSwapspaceProxy.
`arg_options` : | Argument to pass with the method invocation.
`cancellable` : | A GCancellable or `NULL`. [allow-none]

                                                             GDBusMethodInvocation *invocation);

Helper function used in service implementations to finish handling invocations of the `Stop()` D-Bus method. If you instead want to finish handling an invocation by returning an error, use `g_dbus_method_invocation_return_error()` or similar.

This method will free `invocation`, you cannot use it afterwards.

`object` : | A UDisksSwapspace.
`invocation` : | A GDBusMethodInvocation. [transfer full]

### udisks_swapspace_get_active ()

    gboolean            udisks_swapspace_get_active         (UDisksSwapspace *object);

Gets the value of the "Active" D-Bus property.

Since this D-Bus property is readable, it is meaningful to use this function on both the client- and service-side.

`object` : | A UDisksSwapspace.
Returns : | The property value.

### udisks_swapspace_set_active ()

    void                udisks_swapspace_set_active         (UDisksSwapspace *object,
                                                             gboolean value);

Sets the "Active" D-Bus property to `value`.

Since this D-Bus property is not writable, it is only meaningful to use this function on the service-side.

`object` : | A UDisksSwapspace.
`value` : | The value to set.

## Property Details

### The `"active"` property

      "active"                   gboolean              : Read / Write

Represents the D-Bus property "Active".

Since the D-Bus property for this GObject property is readable but not writable, it is meaningful to read from it on both the client- and service-side. It is only meaningful, however, to write to it on the service-side.

Default value: FALSE

## Signal Details

### The `"handle-start"` signal

    gboolean            user_function                      (UDisksSwapspace       *object,
                                                            GDBusMethodInvocation *invocation,

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 `udisks_swapspace_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.

`object` : | A UDisksSwapspace.
`invocation` : | A GDBusMethodInvocation.
`arg_options` : | Argument passed by remote caller.
`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.

### The `"handle-stop"` signal

    gboolean            user_function                      (UDisksSwapspace       *object,
                                                            GDBusMethodInvocation *invocation,

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 `udisks_swapspace_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.

`object` : | A UDisksSwapspace.
`invocation` : | A GDBusMethodInvocation.
`arg_options` : | Argument passed by remote caller.
`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.
