GUID information

[Robert S. Liles]

Is the GUID just random values that I pick or do they actually represent
hard data about the program/routine I am writing? I know that it is
8-4-4-4-12 but I don't know if these groups have any significance at all.

Thank you.

It's random values where the parts are generated individually using
different system values as seeds with the goal being generating a
super-random value that will be guaranteed to be unique across space
and time. For example, it uses the time as the seed for one part and
the mac address for another part. Not sure what other seeds are used,
but that's the basic gist of it.

HTH,

Sam

AFIK, they don't base it on the MAC address anymore. Just a "though
you'd like to know"....

Thank you. I am slowly getting there.
