41 * @is: (out) (allow-none): used to return a #GInputStream
42 * @os: (out) (allow-none): used to return a #GOutputStream
43 * @error: used to raise an error
45 * Return a "pipe to self" connecting @is to @os. This can be used
46 * as a unidirectional pipe to or from a child process, for instance.
48 * See test_bidi_pipe() if you want to emulate a bidirectional pipe
49 * via a pair of unidirectional pipes.
51 * Returns: %TRUE on success

87 * @left: (out) (allow-none): used to return one #GIOStream
88 * @right: (out) (allow-none): used to return the other #GIOStream
89 * @error: used to raise an error
91 * Return two #GIOStream<!---->s connected to each other with pipes.
92 * The "left" input stream is connected by a unidirectional pipe
93 * to the "right" output stream, and vice versa. This can be used
94 * as a bidirectional pipe to a child process, for instance.
96 * See test_pipe() if you only need a one-way pipe.
