### udisks_filesystem_btrfs_proxy_new ()

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

                                       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` . |

If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A UDisksFilesystemBTRFS. |
invocation | A GDBusMethodInvocation. |
arg_name | 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 `Repair()` 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_repair()` 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_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.

### The `“handle-resize”` signal

    gboolean
    user_function (UDisksFilesystemBTRFS *object,
                   GDBusMethodInvocation *invocation,
                   guint64                arg_size,

                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `Resize()` 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_resize()` 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_size | 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 `SetLabel()` 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_set_label()` 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_label | Argument passed by remote caller. |
arg_options | Argument passed by remote caller. |
user_data | user data set when the signal handler was connected. |
