A kernel module is not the same as an application.  You cannot use the
normal C library inside a module, you can only use functions exported
by kernel.  The C routines like fopen() etc. depend on system calls
which obviously can never be called inside a kernel module.

The Book "Linux Device Drivers", 2nd edition is now free (libre), read
the section "Kernel Modules Versus Applications" here:

Hope this helps,
Lokesh.
