write_XLI

Write a model to a file via the External Language Interface.

unsigned char write_XLI(lprec *lp, char *filename, char *options, unsigned char results);

Return Value

write_XLI returns TRUE (1) if the operation was successful. A return value of FALSE (0) indicates an error.

Parameters

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

Filename to write the model to.

options

Extra options that can be used by the writer.

results

FALSE to generate a model file and TRUE to generate a solution file.

Remarks

The write_XLI function writes the model to filename via the External Language Interface. Note that set_XLI must be called before this routine to set an XLI.

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");

  write_XLI(lp, "model.mod", "", FALSE);

  delete_lp(lp);
  return(0);
}
