<h1>read_XLI</h1>
<p>
Create an lprec structure and read a model via the External Language Interface.</p>
<P><B>lprec *read_XLI(char </B>*<I>xliname</I><B>, char </B>*<I>modelname</I><B>, char </B>*<I>dataname</I><B>, char </B>*<I>options</I><B>, int </B><I>verbose</I><B>);</B></P>
<p class="label">
<b>Return Value</b></p>
<p>
Returns a pointer to a new lprec structure. This must be provided to almost all
lp_solve functions.<br>
A <b>NULL</b> return value indicates an error.</p>
<p class="label">
<b>Parameters</b></p>
<P class="dt"><I>xliname</I></P>
<P class="indent">
Filename of the XLI package.
<P class="dt"><I>modelname</I></P>
<P class="indent">
Filename to read the model from.
<P class="dt"><I>dataname</I></P>
<P class="indent">
Filename to read the data from. This may be optional. In that case, set the parameter to NULL.</p>
<P class="dt"><I>options</I></P>
<P class="indent">Extra options that can be used by the reader.</p>
<P class="indent"><i>verbose</i></p>
<p class="indent">The verbose level. Can be one of the following values:<br>
CRITICAL (1), SEVERE (2), IMPORTANT (3), NORMAL (4), DETAILED (5), FULL (6)</p>
<p>See also <A href="set_verbose.htm">set_verbose</A> and <A href="get_verbose.htm">get_verbose</A>.</p>
<p class="label"><b>Remarks</b></p>
<P>
The <b>read_XLI</b> function constructs a
new lprec structure and reads the model from <i>filename</i> via the specified XLI.
See <a href="XLI.htm">External Language Interfaces</a> for a complete description on XLIs.</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;
/* Read LP model */
lp = read_XLI("xli_MathProg", "model.mat", NULL, "", NORMAL);
if(lp == NULL) {
fprintf(stderr, "Unable to read model\n");
return(1);
}
/* Model read */
/*

*/
delete_lp(lp);
return(0);
}
