NAME

blminmax, blmaximum, blminimum – bound of two labels

Synopsis

cc [flag...] file... -ltsol [library...]

#include <tsol/label.h>

void blmaximum(m_label_t *maximum_label, const m_label_t *bounding_label);

void blminimum(m_label_t *minimum_label, const m_label_t *bounding_label);

Description

blmaximum() replaces the contents of label maximum_label with the least upper bound of the labels maximum_label and bounding_label. The least upper bound is the greater of the classifications and all of the compartments of the two labels. This is the least label that dominates both of the original labels.

blminimum() replaces the contents of label minimum_label with the greatest lower bound of the labels minimum_label and bounding_label. The greatest lower bound is the lower of the classifications and only the compartments that are contained in both labels. This is the greatest label that is dominated by both of the original labels.
