### Method

# Fwupd Client update_metadata_bytes_async

since: 1.5.0

#### Declaration [src]

    void
    fwupd_client_update_metadata_bytes_async (
      FwupdClient* self,
      const gchar* remote_id,
      GBytes* metadata,
      GBytes* signature,
      GCancellable* cancellable,
      GAsyncReadyCallback callback,
      gpointer callback_data
    )

#### Description [src]

Updates the metadata. This allows a session process to download the metadata and metadata signing file to be passed into the daemon to be checked and parsed.

The `remote_id` allows the firmware to be tagged so that the remote can be matched when the firmware is downloaded.

NOTE: This method is thread-safe, but progress signals will be emitted in the global default main context, if not explicitly set with `fwupd_client_set_main_context()`.

Available since: 1.5.0

This method completes asynchronously. Use `fwupd_client_update_metadata_bytes_finish()` inside the `GAsyncReadyCallback` to obtain the result of the operation.
