Hi,<br>
<br>
for my evaluation of different kernel modules which rely on randomness I<br>
need the same set of random numbers for each of them.<br>
<br>
Is there any chance that I can get a random number which depends on a<br>
kind of seed value? So if I start with the same seed value, the same<br>
random numbers should be generated.<br>
<br></blockquote><div>If the same numbers are generated, then how can you call it random?<br> <br></div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
Is there any way in the kernel to achieve this?<br>
<br>
Thanks for your hints,<br>
Andreas Leppert<br>
