# get_presolveloops Returns the number of times presolve is done. int get_presolveloops(lprec *lp); Return Value get_presolveloops returns the number of times presolve is done. 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_presolveloops function returns the number of times presolve is done. After a presolve is done, another presolve can again result in elimination of extra rows and/or columns. This number specifies the maximum number of times this process is repeated. By default this is until presolve has nothing to do anymore. Example
    #include <stdio.h>
    #include <stdlib.h>
    #include "lp_lib.h"

    int main(void)
    {
      lprec *lp;
      int presolveloops;

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

      presolveloops = get_presolveloops(lp);

      delete_lp(lp);
      return(0);
    }
