These routines compare two levels to find the sensitivity level that represents the greatest lower bound (blminimum(3TSOL)) or least upper bound (blmaximum(3TSOL)) of the range bounded by the two levels. A level is a classification and set of compartments in a sensitivity label or clearance. Refer to the blminmax(3TSOL) man page.
void blmaximum(blevel_t *maximum_label, const blevel_t *bounding_label); void blminimum(blevel_t *minimum_label, const blevel_t *bounding_label);
