NAME
gethostid - get unique identifier of current host
SYNOPSIS
hostid = gethostid()
long hostid;
DESCRIPTION
Gethostid
returns a CPU identification number which is guaranteed to be
unique for each CPU. This allows third-party software vendors to use
the hostid for copy protection. The hostid is a four byte number with
the first byte being the CPU version (only version 1 exists today) and
the last three bytes are the last three bytes in the ethernet address
(which are guaranteed to be unique).
