This ring extension contains one function only called (newuuid4) this function returns a new random UUID (version 4) whenever it's been called.
This library is a cross platform but I have built and tested it on Ubutnu only.
Note: building this library in Ubuntu requires installation of (uuid-dev) package
sudo apt-get install uuid-dev
Source C library: is this repo.
Have a nice time :)
Enjoy :)
