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.
