## Functions

### udisks_block_vdo_call_deactivate ()

    void
    udisks_block_vdo_call_deactivate (UDisksBlockVDO *proxy,
                                      GVariant *arg_options,
                                      GCancellable *cancellable,
                                      GAsyncReadyCallback callback,
                                      gpointer user_data);

Asynchronously invokes the `Deactivate()` 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_block_vdo_call_deactivate_finish()` to get the result of the operation.

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

#### Parameters

proxy | A UDisksBlockVDOProxy. |
arg_options | Argument to pass with the method invocation. |
cancellable | A GCancellable or `NULL`. | [nullable]
callback | A GAsyncReadyCallback to call when the request is satisfied or `NULL`. |
user_data | User data to pass to `callback` . |

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

#### Parameters

proxy | A UDisksBlockVDOProxy. |
arg_force | Argument to pass with the method invocation. |
arg_options | Argument to pass with the method invocation. |
cancellable | A GCancellable or `NULL`. | [nullable]

## Signal Details

### The `“handle-change-write-policy”` signal

    gboolean
    user_function (UDisksBlockVDO        *object,
                   GDBusMethodInvocation *invocation,
                   gchar                 *arg_write_policy,
                   GVariant              *arg_options,
                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `ChangeWritePolicy()` 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_block_vdo_complete_change_write_policy()` 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 UDisksBlockVDO. |
invocation | A GDBusMethodInvocation. |
arg_write_policy | Argument passed by remote caller. |
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.

Flags: Run Last

Since: 2.8.0

                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `Deactivate()` 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_block_vdo_complete_deactivate()` 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 UDisksBlockVDO. |
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.
