First writing the problem/solution to disk and instantly reading it seems a bit weird. But if this is the only way to provide an inital solution...

The only other way I know to provide an initial solution I find even more awkward... You call glp_intopt(), with presolving disabled, with a callback that calls glp_ios_heur_sol() followed by glp_ios_terminate(). Then you can call glp_intopt() a second time with presolving enabled and the use_sol parameter set.
