Can I use strtok() in a Linux Kernel Module?

Question

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 

        

Answer 1

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. ;)
