There are different types of functions.  For example, fopen is
implemented in user space, while open just moves the arguments into
the right positions and invokes the transition to kernel space, and
sets errno based on the result.  (This is roughly the difference
between section 3 and section 2 of the manual pages.)  Functions like
open are not implemented in C on the user space side.  Whether the
kernel language still counts as C, I'm not sure.
