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.
