随机数生成器，可以在

I'm in need of a C++ (pseudo, i don't care) random number generator that can get me different numbers every time I call the function. This could be simply the way I seed it, maybe there's a better method, but every random generator I've got doesn't generate a new number every time it's called. I've got a need to get several random numbers per second on occasion, and any RNG i plug in tends to get the same number several times in a row. Of course, I know why, because it's seeded by the second, so it only generates a new number every second, but I need to, somehow, get a new number on every call. Can anyone point me in the right direction? I'm in need of a C++ (pseudo, i don't care) ran
