<h1>is_semicont</h1>
<p>Gets the type of the variable. semi-continuous or not.</p>
<p><b>unsigned char is_semicont(lprec </b>*<i>lp</i><b>, int </b><i>column</i><b>);</b></p>
<p class="label"><b>Return Value</b></p>
<p><b>is_semicont</b> returns TRUE (1) if the variable is set as semi-continuous, FALSE (0)
otherwise.<br>
</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">
make_lp</A>, <A HREF="copy_lp.htm">copy_lp</A>, <A href="read_lp.htm">read_lp,
read_LP</A>, <A href="read_mps.htm">read_mps, read_freemps, read_MPS, read_freeMPS</A>, <A HREF="read_XLI.htm">read_XLI</A></p>
<p class="dt"><i>column</i></p>
<p class="indent">The column number of the variable that must be checked. It must
be between 1 and the number of columns in the lp.</p>
<p class="label"><b>Remarks</b></p>
<p>The <b>is_semicont</b> function returns if a variable must be semi-continuous or not. Default
a variable is not semi-continuous.
See <a href="semi-cont.htm">semi-continuous variables</a> for a description about semi-continuous variables.
</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;
unsigned char sc;
/* Create a new LP model */
lp = make_lp(0, 2);
if(lp == NULL) {
fprintf(stderr, "Unable to create new LP model\n");
return(1);
}
sc = is_semicont(lp, 1); /* will return 0 since the variable is not set as semi-continuous at this point */
delete_lp(lp);
return(0);
}
