memset(), fprintf() and others are libc functions. What you need to
do is change your module to use kernel specific functions (since the kernel
can't call user-space functions without some trickery . . .). For example,
change fprintf() to rtl_printf(), and use rtl_printf() just like regular
printf (ie do not specify a filestream to write to).
Also, there is a memset() function in the kernel, just include
asm/string.h in your module to get access to it and other string functions
native to the kernel.
If you want to get really snazzy and make this piece of code work in
user-space or as a module, try using defines, ie
#ifdef MODULE
#define fprintf(stream, format, args...) rtl_printf(format, ## args)
#else /* not a module */
#define fprintf(stream, format, args...) fprintf(stream, format, \
## args)
#endif /* MODULE */
Although you will probably run into other more complicated problems with
making it run in both user-space and kernel.
