### udisks_manager_bcache_proxy_new ()

    void
    udisks_manager_bcache_proxy_new (GDBusConnection *connection,
                                     GDBusProxyFlags flags,
                                     const gchar *name,
                                     const gchar *object_path,
                                     GCancellable *cancellable,
                                     GAsyncReadyCallback callback,
                                     gpointer user_data);

Asynchronously creates a proxy for the D-Bus interface org.freedesktop.UDisks2.Manager.Bcache. 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_manager_bcache_proxy_new_finish()` to get the result of the operation.

See `udisks_manager_bcache_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` . |

### udisks_manager_bcache_proxy_new_finish ()

                                    GError **error);

Finishes an operation started with `udisks_manager_bcache_proxy_new()`.

#### Parameters

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

#### Returns

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

### udisks_manager_bcache_proxy_new_sync ()

    UDisksManagerBcache *

                                          GError **error);

Synchronously creates a proxy for the D-Bus interface org.freedesktop.UDisks2.Manager.Bcache. See `g_dbus_proxy_new_sync()` for more details.

The calling thread is blocked until a reply is received.

See `udisks_manager_bcache_proxy_new()` for the asynchronous 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]

## Signal Details

### The `“handle-bcache-create”` signal

    gboolean
    user_function (UDisksManagerBcache   *object,
                   GDBusMethodInvocation *invocation,
                   char                  *arg_backing_dev,
                   char                  *arg_cache_dev,
                   GVariant              *arg_options,
                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `BcacheCreate()` 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_manager_bcache_complete_bcache_create()` 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 UDisksManagerBcache. |
invocation | A GDBusMethodInvocation. |
arg_backing_dev | Argument passed by remote caller. |
arg_cache_dev | 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.
