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
The blmaximum() function replaces the contents of label maximum_label with the least upper bound of the labels maximum_label and bound-
ing_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.
The blminimum() function replaces the contents of label minimum_label with the greatest lower bound of the labels minimum_label and bound-
ing_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.
