### udisks_filesystem_btrfs_proxy_new ()

    void
    udisks_filesystem_btrfs_proxy_new (GDBusConnection *connection,
                                       GDBusProxyFlags flags,
                                       const gchar *name,

                                       GAsyncReadyCallback callback,
                                       gpointer user_data);

Asynchronously creates a proxy for the D-Bus interface org.freedesktop.UDisks2.Filesystem.BTRFS. See `g_dbus_proxy_new()` for more details.

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_filesystem_btrfs_proxy_new_finish()` to get the result of the operation.

See `udisks_filesystem_btrfs_proxy_new_sync()` for the synchronous, blocking version of this constructor.

#### Parameters

connection | A GDBusConnection. |
flags | Flags from the GDBusProxyFlags enumeration. |
name | A bus name (well-known or unique) or `NULL` if `connection` is not a message bus connection. | [nullable]
object_path | An object path. |
cancellable | A GCancellable or `NULL`. | [nullable]
callback | A GAsyncReadyCallback to call when the request is satisfied. |
user_data | User data to pass to `callback` . |

Finishes an operation started with `udisks_filesystem_btrfs_proxy_new()`.

#### Parameters

res | The GAsyncResult obtained from the GAsyncReadyCallback passed to `udisks_filesystem_btrfs_proxy_new()`. |
error | Return location for error or `NULL` |

#### Returns

The constructed proxy object or `NULL` if `error` is set.

                                    gpointer user_data);

Like `udisks_filesystem_btrfs_proxy_new()` but takes a GBusType instead of a GDBusConnection.

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_filesystem_btrfs_proxy_new_for_bus_finish()` to get the result of the operation.

    const gchar *
    udisks_filesystem_btrfs_get_label (UDisksFilesystemBTRFS *object);

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

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

The returned value is only valid until the property changes so on the client-side it is only safe to use this function on the thread where `object` was constructed. Use `udisks_filesystem_btrfs_dup_label()` if on another thread.

#### Parameters

object | A UDisksFilesystemBTRFS. |

#### Returns

The property value or `NULL` if the property is not set. Do not free the returned value, it belongs to `object` .

You can then call `udisks_filesystem_btrfs_call_create_snapshot_finish()` to get the result of the operation.

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

#### Parameters

proxy | A UDisksFilesystemBTRFSProxy. |
arg_source | Argument to pass with the method invocation. |
arg_dest | Argument to pass with the method invocation. |
arg_ro | Argument to pass with the method invocation. |

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_filesystem_btrfs_call_resize_finish()` to get the result of the operation.

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

#### Parameters

proxy | A UDisksFilesystemBTRFSProxy. |
arg_size | Argument to pass with the method invocation. |
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` . |

                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `AddDevice()` 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_filesystem_btrfs_complete_add_device()` 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 UDisksFilesystemBTRFS. |
invocation | A GDBusMethodInvocation. |
arg_device | 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 `CreateSnapshot()` 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_filesystem_btrfs_complete_create_snapshot()` 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

                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `RemoveDevice()` 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_filesystem_btrfs_complete_remove_device()` 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 UDisksFilesystemBTRFS. |
invocation | A GDBusMethodInvocation. |
arg_device | 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.
