Guys, motivated by the previous discussion on unix C, which was reminiscent of those good old days when I worked on Unix., here I give you guys a couple of more typical interview questions I used to ask at interviews:

1) how to create a daemon process
2)How do you achieve interprocess communication(IPC), give me
an example to illustrate how you can use unamed pipe to make two
processes talk.
3)What is the difference between kernel and user threads?

.... list goes on..
