# copy_lp Copy an existing lprec structure to a new lprec structure. lprec *copy_lp(lprec *lp); 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 not enough memory available to setup an lprec structure. 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 copy_lp function constructs a new LP from an existing lp structure. The new structure is independent from the original one. Example
    #include <stdio.h>
    #include <stdlib.h>
    #include "lp_lib.h"

    int main(void)
    {
      lprec *lp, *lpcopy;

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

      /* Model created */

      /*

      .
      .
      */

      lpcopy = copy_lp(lp);

      /*
      .
      .
      .
      */

      delete_lp(lp);
      delete_lp(lpcopy);

      return(0);
    }
