Well you can't just use libc functions in kernel space -- this is a
basic premise of kernel programming. Some of the standard libc functions
are 'emulated' as you will in the kernel internal static library, sources
of which are found in /usr/src/sys/libkern. Might I suggest you read up
on kernel programming a bit, for example by reading Kirk McKusick's 4.4BSD
