# set_XLI Set External Language Interfaces package. unsigned char set_XLI(lprec *lp, char *filename); Return Value set_XLI returns TRUE if the call has succeeded, else FALSE. Parameters lp Pointer to previously created lp model. See return value of make_lp, copy_lp, read_lp, read_LP, read_mps, read_freemps, read_MPS, read_freeMPS, read_XLI filename The name of the XLI package. Remarks The set_XLI function sets the External Language Interface (XLI). This call is normally only needed when write_XLI will be called. read_XLI automatically calls this routine. See External Language Interfaces for a complete description on XLIs. Example
    #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");

      delete_lp(lp);
      return(0);
