Mersenne Twister pseudorandom number generator under Ubuntu

Hello all!
I need to generate Mersenne Twister pseudorandom number generator and
I can't understand how to use /dev/random or /dev/urandom.I guess that is much better than srand(time(NULL))

Thanx!

I think you're correct /dev/random much better than srand.

What are you going to be using it for ? As it is pseudorandom non-cryptographic, you can just use the system time.

I'm not sure that seed generated by this way can be use for generation any random distribution function...Besides, I guess that use native linux feature it's more right approach.

The output data is definitely going to be randomly distributed, as long as the seed is not the same every time. Using the time or /dev/urandom means that the seed won't be the same every time you run it.
