     NAME
          gethostid, sethostid - get/set unique identifier of  current
          host

     SYNOPSIS

          int hostid;

     DESCRIPTION
          sethostid establishes a 32-bit identifier for the current
          processor.  This identifier is intended to be unique among
          all systems in existence and is normally a DARPA Internet
          address for the local machine.  This call is allowed only to
          the superuser and is normally performed at boot time.

     RETURN VALUE
          gethostid returns the 32-bit identifier for the current pro-
          cessor.

          sethostid returns zero upon successful completion and -1
          upon error.

     SEE ALSO
          hostid(1N), gethostname(2N).

     BUGS
          32 bits for the identifier is too small.
