title: Read/write file pipes in vala/glib
body: <p>I am using the glib vala function glib.process.spawn_async_with_pipes()(<a href="http://references.valadoc.org/#!api=glib-2.0/GLib.Process.spawn_async_with_pipes" rel="nofollow">http://references.valadoc.org/#!api=glib-2.0/GLib.Process.spawn_async_with_pipes</a>), which outputs some ints corresponding to stdin, stdout, and stderr. How would I use these pipes in Vala?</p>
