<b>Remarks</b></p>
<P>
The <b>write_XLI</b> function writes the model to <i>filename</i> via the External Language Interface.
Note that <a href="set_XLI.htm">set_XLI</a> must be called before this routine to set an XLI.
</P>
See <a href="XLI.htm">External Language Interfaces</a> for a complete description on XLIs.

<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(0, 0);
if(lp == NULL) {
fprintf(stderr, "Unable to create new LP model\n");
return(1);
}
set_XLI(lp, "xli_MathProg");
write_XLI(lp, "model.mod", "", FALSE);
