51 * @name Standard Stream Objects
52 *
53 * The &lt;iostream&gt; header declares the eight <em>standard stream
54 * objects</em>. For other declarations, see
55 * http://gcc.gnu.org/onlinedocs/libstdc++/27_io/howto.html#10 and the
56 * @link s27_2_iosfwd I/O forward declarations @endlink
57 *
58 * They are required by default to cooperate with the global C library's
59 * @c FILE streams, and to be available during program startup and
60 * termination. For more information, see the HOWTO linked to above.
