Unfortunately, glpk 4.52 doesn't have such routines, sorry. Two api
routines glp_get_it_cnt and glp_set_it_cnt will appear in a next version
of the package.

As a workaround you could use the following code:

#include <glpk.h>
typedef struct DMP DMP;
typedef struct GLPROW GLPROW;
typedef struct GLPCOL GLPCOL;
typedef struct AVL AVL;
typedef struct BFD BFD;
[copy here declaration of struct glp_prob from glpk/src/glpapi.h]
int glp_get_it_cnt(glp_prob *P) { return P->it_cnt; }

Hope this resolves the issue. Thanks.
