Accurate ? I don't think that word has anything to do with random number generators.

Complicated ? Well, I'm sure you can find more complicated ones on the internet, but I don't think the complexity of a random number generator has anything to do with how good it is.

I recommend you just use some bytes out of '/dev/urandom' as a seed for the rand and srand functions. I've written a C program for this myself, but you need C++. If you want I'll post the C one I wrote.

Could you be a bit more specific about what you really need. Maybe knowing why you need it or what it will be used for will help.
