.. currentmodule:: gi.repository.Gio





.. class:: DataOutputStream(**properties: ~typing.Any)
   :no-contents-entry:


Superclasses: :class:`~gi.repository.Gio.FilterOutputStream`, :class:`~gi.repository.Gio.OutputStream`, :class:`~gi.repository.GObject.Object`



Implemented Interfaces: :class:`~gi.repository.Gio.Seekable`



Data output stream implements :obj:`~gi.repository.Gio.OutputStream` and includes functions
for writing data directly to an output stream.


Constructors
------------

.. rst-class:: interim-class

.. class:: DataOutputStream
   :no-index:

      Creates a new data output stream for ``base_stream``\.






      :param base_stream: a :obj:`~gi.repository.Gio.OutputStream`\.
