This is probably easy:
I have to get the "unique-id" or "machine-id", but want my code to
be as portable as possible.
I found gethostid() to work, under SunOs (and probably any BSD-like Unix ???)
and uname() under HP/UX (and probably any SysV ???).
Am I right, or there are more secrets(?!) behind the scenes???
Thanks in advance.
