# has_XLI Returns if there is an external language interface (XLI) set. unsigned char has_XLI(lprec *lp); Return Value has_XLI returns TRUE if there is an XLI set, 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 Remarks 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;
      unsigned char hasXLI;

      /* Create a new LP model */
      lp = make_lp(0, 0);
      if(lp == NULL) {
        fprintf(stderr, "Unable to create new LP model\n");
        return(1);
      }

      hasXLI = has_XLI(lp);

      delete_lp(lp);
      return(0);
