<h1>get_solutioncount</h1>
<p>Returns the number of equal solutions.</p>
<p><b>int get_solutioncount(lprec </b>*<i>lp</i><b>);</b></p>
<p class="label"><b>Return Value</b></p>
<p><b>get_solutioncount</b> returns the number of equal solutions. This is only
valid if there are integer, semi-continious or SOS variables in the model so
that the branch-and-bound algoritm is used. This count gives the number of
solutions with the same optimal objective value. If there is only one optimal
solution, this value is 1.
</p>
<p class="label"><b>Parameters</b></p>
<p class="dt"><i>lp</i></p>
<p class="indent">Pointer to previously created lp model. See return value of <A href="make_lp.htm">

<p class="label"><b>Remarks</b></p>
<p>The <b>get_solutioncount</b> function returns the number of equal solutions up
to <A href="get_solutionlimit.htm">get_solutionlimit</A>.
</p>
<p class="label"><b>Example</b></p>
<pre><code>#include <stdio.h>
#include <stdlib.h>
#include "lp_lib.h"
int main(void)
{
lprec *lp;
int solutioncount;
/* Create a new LP model */
