link question

I have a quick question; this is something I haven't been able to figure out. By using the kernel headers you can call functions that are defined in the kernel, but you don't actually have to link to the kernel or any sort of library. How does this work? How does compiled code call the function if it doesn't link to it in some way or another?. -- Take care, Ty my website: http://tds-solutions.net my blog: http://tds-solutions.net/blog skype: st8amnd127 My programs don't have bugs; they're randomly added features!
