I need to do a parse on the data written to my module, and the use of the strtok() function of string.h would be useful. However I've tried
#include <string.h>
and
#include <linux/string.h>
with no success. Is this possible? Or will I have to write my own strtok function?
Thanks

You can try lsmod | grep <module name> to see all loaded kernel modules that are using a module. You can also try dmesg | grep <module name> to see if the kernel logs have any clues as to which processes may be using a module.
In computing, a loadable kernel module (LKM) is an object file that contains code to extend the running kernel, or so-called base kernel, of an operating system. LKMs are typically used to add support for new hardware (as device drivers) and/or filesystems, or for adding system calls.
The kernel does not have a main function. main is a concept of the C language. The kernel is written in C and assembly. The entry code of the kernel is written by assembly.
The latest kernel library has this, which may do what you need:
/**
* strsep - Split a string into tokens
* @s: The string to be searched
* @ct: The characters to search for
*
* strsep() updates @s to point after the token, ready for the next call.
*
* It returns empty tokens, too, behaving exactly like the libc function
* of that name. In fact, it was stolen from glibc2 and de-fancy-fied.
* Same semantics, slimmer shape. ;)
