[Coin-ipopt] (no subject)

Hi,all:

I'm using ipopt under ampl.

Any one know how to write the optimal solution to a file rather than
using the command "display "?

(I noted "void AmplTNLP::write_solution_file" call
  write_sol(cmessage, x_sol_, lambda_sol_, NULL);
 But I don't know how to use this in ampl.
)

Thanks!
