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?.
you need to look closer....for example include/linux/mm.h. There you will see definition of constants and functions used for memory management. So, what library here means IMHO are group of headers that contains the needed functions/definitions by themselves. Linking? I think it's better named as "including"...indeed there are linking process during kernel build, but that is just a way to build final image using several objects which originated from the practice of refactoring etc. kindly CMIIW people... -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
