[Coin-lpsolver] Fixed variables

I am doing column generation using Symphony and CLP solver.
I first try to solve the Restricted Master Problem to IP optimal, then I
would like to use the reduced cost from that solution to price the columns.
But to do that, I need to get dual/shadow prices from that RMP IP solution.
I can't seem to find a way to fix the variables to the IP solution (so that
I can use CLP to solve it as LP-fixed.)
Anybody can give me some ideas or suggestions.
Thank you for your time.
