## Functions

### udisks_encrypted_interface_info ()

    GDBusInterfaceInfo *
    udisks_encrypted_interface_info (void);

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

#### Returns

A GDBusInterfaceInfo. Do not free.

[transfer none]

### udisks_encrypted_override_properties ()

Overrides all GObject properties in the UDisksEncrypted interface for a concrete class. The properties are overridden in the order they are defined.

#### Parameters

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

#### Parameters

proxy | A UDisksEncryptedProxy. |
arg_passphrase | Argument to pass with the method invocation. |

## Property Details

### The `“child-configuration”` property

      “child-configuration”      GVariant *

Represents the D-Bus property "ChildConfiguration".

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.

Flags: Read / Write

Allowed values: GVariant<a(sa{sv})>

Default value: NULL

## Signal Details

### The `“handle-change-passphrase”` signal

    gboolean
    user_function (UDisksEncrypted       *object,
                   GDBusMethodInvocation *invocation,
                   gchar                 *arg_passphrase,
                   gchar                 *arg_new_passphrase,
                   GVariant              *arg_options,
                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `ChangePassphrase()` 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_encrypted_complete_change_passphrase()` 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 UDisksEncrypted. |
invocation | A GDBusMethodInvocation. |
arg_passphrase | Argument passed by remote caller. |
arg_new_passphrase | 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

### The `“handle-lock”` signal

    gboolean
    user_function (UDisksEncrypted       *object,
                   GDBusMethodInvocation *invocation,
                   GVariant              *arg_options,
                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `Lock()` 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_encrypted_complete_lock()` 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 UDisksEncrypted. |
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.

Flags: Run Last

### The `“handle-unlock”` signal

    gboolean
    user_function (UDisksEncrypted       *object,
                   GDBusMethodInvocation *invocation,
                   gchar                 *arg_passphrase,
                   GVariant              *arg_options,
                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `Unlock()` 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_encrypted_complete_unlock()` 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 UDisksEncrypted. |
invocation | A GDBusMethodInvocation. |
arg_passphrase | 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.
