set_row_name

# set_row_name Set the name of a constraint (row) in the lp. unsigned char set_row_name(lprec *lp, int row, char *new_name); Return Value set_row_name returns TRUE (1) if the operation was successful. A return value of FALSE (0) indicates an error. 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 row The row for which the name must be set. Must be between 0 and the number of rows in the lp. new_name The name for the row. Remarks The set_row_name sets the name of the row. The row must already exist. row 0 is the objective function. Row names are optional. Example
    #include <stdio.h>
    #include <stdlib.h>
    #include "lp_lib.h"

    int main(void)
    {
      lprec *lp;

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

      set_row_name(lp, 1, "row1");

      delete_lp(lp);
      return(0);
