[Clp] How to provide an initial feasible x?

Hi,

I'm solving the following kind of problem:
min c^T x
s.t. Ax = b
x >= 0

And I can provide an initial x which fulfills Ax=b, but I don't know how
to hand it to the solver.

Currently I'm doing this:

    // Create the simplex solver and load the problem.
    ClpSimplex m;
    m.setLogLevel(0);
    m.loadProblem(cols + 2*rows, rows, start.data(), indices.data(),
values.data(), collb.data(), NULL, obj_c.data(), b.memptr(), b.memptr(),
NULL);
    m.dual();

How can I provide the solver with the initial feasible x?

Best Regards,
Alexander
