<blockquote><p>These functions return a pointer to the state of generator <var>r</var> and
its size. You can use this information to access the state directly. For
example, the following code will write the state of a generator to a
stream,
<pre class="example"> void * state = gsl_qrng_state (q);
size_t n = gsl_qrng_size (q);
fwrite (state, n, 1, stream);
</pre>
