[Help-glpk] about dual value

[cen zhihao]

Hello

I use glpk to solve a MIP problem : 

min c1 * x + c2 * y
A1 * x + A2 * y <= b
(x is a vector of integer, y is a vector of real value)

After having solved the mip problem succefully (optimal solution : x = x' and y 
= y'), 
I want to have the dual value of b with relaxing problem to continuous one and 
keep 
the solution at (x', y').

Is there a function if GLPK giving this informaion? Or someone can help me to 
calculate these
values.

Many thanks.
