reading /dev/mem - questions

[Dylan Rhodes]

	Okay, so now that I have root access and everything, I thought
I'd write my own version of 'w' - that is, a program that tells me
who's on, and what they're doing.

	From what I can gather, w and ps get this information from
reading memory, from /dev/mem and/or /dev/kmem.

Questions:

	- Am I on the right track?

	- What *is* the difference between /dev/mem and /dev/kmem?

	- Does anybody have the source code to a 'w' or 'ps' program
	  that I can peruse?
