Is it possible to enumerate the neighboring feasible solutions of the
solution of an lp?

You may perform the post-optimal analysis by specifying the '--ranges'
option for glpsol, or with the routine glp_print_ranges. For more
details please see the glpk reference manual, Section 3.4 "Post-optimal
analysis routines".

My suspicion is that OP wants to do it through
the API so that he can process the vertices.
