# set_lag_trace Sets a flag if Lagrangian progression must be printed while solving. void set_lag_trace(lprec *lp, unsigned char lag_trace); Return Value set_lag_trace has no return value. 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 lag_trace TRUE or FALSE. Print or do not print. Remarks The set_lag_trace function sets a flag if Lagrangian progression must be printed while solving. This function is mend for debugging purposes. The default is not to print (FALSE). 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_lag_trace(lp, TRUE);

      delete_lp(lp);
      return(0);
    }
