Description

   This function generates and returns a universally unique identifier (UUID),
   which is almost guaranteed to be unique across time and all clients. The
   identifier is created from a combination of the computer's hardware
   characteristics, the current time, and a sequence number. Characteristics of
   the actual feature data are not used to assist in UUID generation.

   The UUID is expressed as a string consisting of:

      8 hexadecimal digits followed by a hyphen

      three groups of 4 hexadecimal digits, each followed by a hyphen

      12 hexadecimal digits

   UUIDs are 36 bytes in size and look like:

   7672aac8-fa0b-464c-b0b8-3efa9ae9cd86
   6689a182-e611-4021-a6e6-3cfb7c5d48dc

   This function is currently only supported on the following operating systems:
   Windows (all variants), Linux, Solaris, and Mac OS X. When invoked on other
   operating systems, it will return an error.
