Alternatively and maybe more portable, libuuid (should be part of all
decent systems too) could be a first choice. BSD also provides
compliant APIs as part of their libc
(https://www.freebsd.org/cgi/man.cgi?query=uuid for freebsd f.e.). On
Windows

UuidCreate and UuidToString should do it but I did not check their
compliance yet.

For the reference here: by compliant, I mean compliant with
https://tools.ietf.org/html/rfc4122
