# read_mps, read_freemps, read_MPS, read_freeMPS Create an lprec structure and read an mps model from file. lprec *read_mps(FILE *stream, int verbose); lprec *read_freemps(FILE *stream, int verbose); lprec *read_MPS(char *filename, int verbose); lprec *read_freeMPS(char *filename, int verbose); Return Value Returns a pointer to a new lprec structure. This must be provided to almost all lp_solve functions. A NULL return value indicates an error. Specifically file could not be opened or file has wrong structure or not enough memory available to setup an lprec structure. Parameters stream Pointer to FILE structure. filename Filename to read the mps model from. verbose The verbose level. Can be one of the following values: CRITICAL (1), SEVERE (2), IMPORTANT (3), NORMAL (4), DETAILED (5), FULL (6) See also set_verbose and get_verbose. Remarks The read_mps, read_freemps, read_MPS, read_freeMPS functions construct a new lprec structure and read the model from filename. read_mps, read_freemps need a file pointer to an already opened file. read_MPS, read_freeMPS accepts the name of the file. The latter functions will generally be more convenient. The model in the file must be in mps-format. The read_free* routines accept files in free MPS format. The other routines accept files in fixed MPS format. It is advised not to read/write the lprec structure. Instead, use the function interface to communicate with the lp_solve library. This because the structure can change over time. The function interface will be more stable. Example
    #include <stdio.h>
    #include <stdlib.h>
    #include "lp_lib.h"
    int main(void)
    {
      lprec *lp;

      /* Read MPS model */
      lp = read_MPS("model.mps", NORMAL);
      if(lp == NULL) {
        fprintf(stderr, "Unable to read model\n");
        return(1);
      }

      /* Model read */

      /*

      delete_lp(lp);
      return(0);
    }
