OutputStream.writeBytes

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

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