Whenever you -need a stream of reproducible random numbers, you better create a -<a class="link" href="glib-Random-Numbers.html#GRand" title="GRand"><span class="type">GRand</span></a> yourself and use the <code class="function">g_rand_*</code> functions -directly, which will also be slightly faster. Initializing a <a class="link" href="glib-Random-Numbers.html#GRand" title="GRand"><span class="type">GRand</span></a> -with a certain seed will produce exactly the same series of random -numbers on all platforms.
