Hello,

   I need information about few things, I hope someone can help
me and thanks in advance.

a) Is there any function or variable that tells me which is the
   root user UID in the system, or root always have 0 and it's
   an "elegant" option to compare the variables or structure
   members against zero.
b) Can normal users look for system processes or kernel threads?
c) Can root look for system processes or kernel threads?

Regards,
