blminmax(3TSOL) Trusted Extensions Library Functions blminmax(3TSOL) 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.

blcompare(3TSOL) Trusted Extensions Library Functions blcompare(3TSOL) NAME
blcompare, blequal, bldominates, blstrictdom, blinrange - compare binary labels SYNOPSIS
cc [flag...] file... -ltsol [library...] #include <tsol/label.h> int blequal(const m_label_t *label1, const m_label_t *label2); int bldominates(const m_label_t *label1, const m_label_t *label2); int blstrictdom(const m_label_t *label1, const m_label_t *label2); int blinrange(const m_label_t *label, const brange_t *range); DESCRIPTION
These functions compare binary labels for meeting a particular condition. The blequal() function compares two labels for equality. The bldominates() function compares label label1 for dominance over label label2. The blstrictdom() function compares label label1 for strict dominance over label label2. The blinrange() function compares label label for dominance over range->lower_bound and range->upper_bound for dominance over level label. RETURN VALUES
These functions return non-zero if their respective conditions are met, otherwise zero is returned. ATTRIBUTES
