Help please...random() in kernel? and Links?
1.Why is it not possible to use random() in kernel code? If the kernel cannot do that, what is going on when kernel code contains calls to printf(), it works fine?
2.Symbolic links in Linux and Unix can cross partition boundaries, but hard links cannot. Can somebody explain this to me?
Thank you
