<p>The following function can be used to access the elements of a combination.

<dl>
<dt><a name="index-gsl_005fcombination_005fget"></a>Function: <em>size_t</em> <strong>gsl_combination_get</strong> <em>(const gsl_combination * <var>c</var>, const size_t <var>i</var>)</em></dt>
<dd><p>This function returns the value of the <var>i</var>-th element of the
combination <var>c</var>. If <var>i</var> lies outside the allowed range of 0 to
<em><var>k</var>-1</em> then the error handler is invoked and 0 is returned. An inline version of this function is used when <code>HAVE_INLINE</code> is defined.
