<b>Remarks</b></p>
<p>
The <b>print_constraints</b> function prints the values of the constraints of the lp.
This can only be done after a successful solve.<br>
This function is meant for debugging purposes. By default, the output is stdout. However
this can be changed via a call to <A href="set_output.htm">set_outputstream, set_outputfile</A>.

<p class="label">
<b>Example</b></p>
<pre><code>#include <stdio.h>
#include <stdlib.h>
#include "lp_lib.h"
int main(void)
{
lprec *lp;
/* Create a new LP model */
lp = make_lp(1, 1);
if(lp == NULL) {
fprintf(stderr, "Unable to create new LP model\n");
return(1);
}
solve(lp);
print_constraints(lp, 1);
delete_lp(lp);
return(0);
}
