[Help-glpk] qustion about reduced cost

[Jonata Goulart]

At glpapi7.c there is the rotine glp_simplex2() and two vector bbar and cbar 
(reduced cost of the basic and non basic variable as described on the 
comments). Based on this two vectors, How would I know which variables are 
basic and which are non basic?

Exemple:

In my application I have 8 structural variables named x1..x8 (the number of 
constraints are 8) and at i-th iteration of glp_simplex2 there are
* 8 basic variables and 9 non basic variables.
whitch of my x1..x8 are basic and which aren't?

I need to store the reduced cost of my structural variables at a specific 
iteration so, i need to know that.
