It would require too much control parameters, so using callback is
a more appropriate way.

void cb_func(glp_tree *tree, void *info)
{ if (glp_ios_reason(tree) == GLP_IBINGO)
glp_ios_terminate(tree);
return;
}
And somewhere in main():
glp_prob *mip;
glp_iocp parm;
. . .
glp_simplex(mip, NULL);
glp_init_iocp(&parm);
parm.cb_func = cb_func;
glp_intopt(mip, &parm);
. . .
