OutputStream.writeBytes

A wrapper function for gio.output_stream.OutputStream.write which takes a #GBytes as input. This can be more convenient for use by language bindings or in other cases where the refcounted nature of #GBytes is helpful over a bare pointer interface.

However, note that this function may still perform partial writes, just like gio.output_stream.OutputStream.write. If that occurs, to continue writing, you will need to create a new #GBytes containing just the remaining bytes, using glib.bytes.Bytes.newFromBytes. Passing the same #GBytes instance multiple times potentially can result in duplicated data in the output stream.
