Creating the same random numbers

[Enrico Granata]

Apart from the obvious consideration that repeating numbers are NOT random anymore, I guess what the original question asker wanted to know is:

I need to generate some random numbers (so I need a PRNG). Then, I need to save these random numbers somewhere so I can use them over and over again to check some kernel modules.
Can't you simply write a C program that generates, say, 1 million random values, writes them to a file, and then use them?
