<p class="label"><b>Remarks</b></p>
<p><b>The Lagrangian solver does not work. Do not use this call.</b></p>
<p>The <b>get_Lrows</b> function returns the number of Lagrangian rows in the lp.<br>
A Lagrangian row is added via <A HREF="add_lag_con.htm">add_lag_con</A>.
</p>
<p class="label"><b>Example</b></p>
<pre><code>#include <stdio.h>
#include <stdlib.h>
#include "lp_lib.h"
int main(void)

int Lrows;
/* Create a new LP model */

Lrows = get_Lrows(lp); /* Will return 1 */
