[Coin-lpsolver] Initializing Clp to a known solution

Hi !
I set up a problem for Clp for which I know an optimum solution, and I
would like to initialize Clp so that doing initialSolve() (or resolve())
will not change the solution from the one I know.
(I do this to generate cutting planes that cut off this particular solution)
I specified my solution using setColSolution() and tried for a few days
to use setBasis() and setRowPrice() to set up a "reasonnable" basis, but
did not succeed (it works in most case but not all : in a few cases Clp
moves to another optimal solution).
Is there a simple solution to make Clp accept a known solution and not
move away from it ?
Thank you very much in advance !
Regards,
Jean-Sébastien
