30 * @short_description: A wrapper around an input and an output stream.
32 * @see_also: #GIOStream
34 * GSimpleIOStream creates a #GIOStream from an arbitrary #GInputStream and
35 * #GOutputStream. This allows any pair of input and output streams to be used
36 * with #GIOStream methods.
38 * This is useful when you obtained a #GInputStream and a #GOutputStream
39 * by other means, for instance creating them with platform specific methods as
40 * g_unix_input_stream_new() or g_win32_input_stream_new(), and you want
41 * to take advantage of the methods provided by #GIOStream.
49 * A wrapper around a #GInputStream and a #GOutputStream.
