<title>Description</title>
<para>
<link linkend="class-giounixoutputstream"><classname>gio.unix.OutputStream</classname></link>
implements <link linkend="class-giooutputstream"><classname>gio.OutputStream</classname></link>
for writing to a UNIX file descriptor, including asynchronous operations.
The file descriptor must be selectable, so it doesn't work with opened files.
</para>
<para>
Note that <link linkend="class-giounixoutputstream"><classname>gio.unix.OutputStream</classname></link>
belongs to the UNIX-specific GIO interfaces, thus you have to use the gio-unix-2.0.pc pkg-config file
when using it.
