CONFORMING TO         top

       The Linux pcp-ipcs utility is not fully compatible to the POSIX pcp-
       ipcs utility.  The Linux version does not support the POSIX -a, -b
       and -o options, but does support the -l and -u options not defined by
       POSIX.  A portable application shall not use the -a, -b, -o, -l, and
       -u options.
