kernel code?

[tyler]

Hay,
I just got the latest code for the kernel.
I have a question,
I am trying to add some stuff, and make some programs that use some 
functions in the kernel. I was looking at the kernel and am able to 
understand what it does (with the functions and stuff) I get it, but, how do 
you know where the functions and data types and structures are that you 
want? I just don't know where to find everything that I need to code what I 
want. I can code it, that is no problem for me, its just the tracking it 
down. I haven't ever had something this big on my hands, and when I look at 
all the files, they make some sense, but it looks a bit confusing as to what 
does what, and where I should put what when I code it.

Also, when I type make, I get the following errors.
well. I got the error that there was no .config file, so I just created a 
blank, because I didn't want to deal with it.
Do I have to write a file? if so, does someone know where I could get a 
template on how/where to?
Also, upon compilation, will it compile for the computer I am on? I want it 
to be cross-compatible.
Last thing. If I do get a successfull make, it won't replace the current 
kernel will it?
Thanks,
Tyler Littlefield.
