# get_objective Returns the value of the objective function. REAL get_objective(lprec *lp); Return Value get_objective returns the value of the objective. 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 The get_objective function returns the value of the objective of the last solve. This value is only valid after a successful solve or lag_solve. Example
    #include <stdio.h>
    #include <stdlib.h>
    #include "lp_lib.h"

    int main(void)
    {
      lprec *lp;
      REAL obj;

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

      solve(lp);

      obj = get_objective(lp);

      delete_lp(lp);
      return(0);
    }
