Trusted Extensions Library Functions              blminmax(3TSOL)



NAME
     blminmax, blmaximum, blminimum - bound of two labels

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


     #include 

     void blmaximum(mlabelt *maximumlabel,
          const mlabelt *boundinglabel);


     void blminimum(mlabelt *minimumlabel,
          const mlabelt *boundinglabel);


DESCRIPTION
     The blmaximum() function  replaces  the  contents  of  label
     maximumlabel  with  the  least  upper  bound  of the labels
     maximumlabel and boundinglabel. The least upper  bound  is
     the  greater  of the classifications and all of the compart-
     ments of the two labels. This is the least label  that  dom-
     inates both of the original labels.


     The blminimum() function  replaces  the  contents  of  label
     minimumlabel  with  the  greatest lower bound of the labels
     minimumlabel and boundinglabel. The greatest  lower  bound
     is  the  lower  of the classifications and only the compart-
     ments that  are  contained  in  both  labels.  This  is  the
     greatest  label  that  is  dominated by both of the original
     labels.
