When the operation is finished, `callback` will be invoked in the thread-default main loop of the thread you are calling this method from (see `g_main_context_push_thread_default()`). You can then call `udisks_block_call_get_secret_configuration_finish()` to get the result of the operation.

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

#### Parameters

proxy | A UDisksBlockProxy. |
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` . |

## Signal Details

### The `“handle-add-configuration-item”` signal

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

Signal emitted when a remote caller is invoking the `AddConfigurationItem()` 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_complete_add_configuration_item()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no other signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A UDisksBlock. |
invocation | A GDBusMethodInvocation. |
arg_item | Argument passed by remote caller. |
arg_options | Argument passed by remote caller. |
user_data | user data set when the signal handler was connected. |

#### Returns

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

Flags: Run Last

### The `“handle-format”` signal

                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `Format()` 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_complete_format()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no other signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A UDisksBlock. |
invocation | A GDBusMethodInvocation. |
arg_type | Argument passed by remote caller. |
arg_options | Argument passed by remote caller. |
user_data | user data set when the signal handler was connected. |

#### Returns

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

                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `GetSecretConfiguration()` 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_complete_get_secret_configuration()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no other signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A UDisksBlock. |
invocation | A GDBusMethodInvocation. |
arg_options | Argument passed by remote caller. |
user_data | user data set when the signal handler was connected. |

                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `OpenForBenchmark()` 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_complete_open_for_benchmark()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no other signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A UDisksBlock. |
invocation | A GDBusMethodInvocation. |
fd_list | A GUnixFDList or `NULL`. | [nullable]
arg_options | Argument passed by remote caller. |
user_data | user data set when the signal handler was connected. |

#### Returns

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