In standard c++, how to generate GUID?
In windows, I know I have API to create. But I would like to be platform independent, is there a way?

There must be a standard and recommendations. I would google for UUID. Maybe start with Wikipedia. – Cheers and hth. - Alf Oct 25 '14 at 15:22

Check this link. It might help you to solve your problem: http://stackoverflow.com/questions/3247861/example-of-uuid-generation-using-boost-in-c/3248017#3248017 – Tequila Oct 25 '14 at 15:42

You could try [Boost.Uuid](http://www.boost.org/doc/libs/1_56_0/libs/uuid/) – Chris Drew Oct 25 '14 at 15:50

The GUID refers to Microsoft's implementation of the Universal Unique IDentifier (UUID) defined by RFC 4122.
So for the Microsoft implementation there is no portable way to generate it: it's windows API. It's 16 bytes as UUID, but there are some differences in the byte order.
But if you are looking for UUID, boost provides a portable implementation.
