Getting kernel symbols in kernel module (dynamically)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I want to call the kernel function sys_clock_gettime, but when I just try to call it, the linker complains about the unknown symbol/function sys_clock_gettime, so i have hard coded a function pointer in my module...:

long (*p_sys_clock_gettime)(clockid_t, struct timespec *tp) = 0xc004373c;

That works fine for my system, but I know thats not the way to do it. How is it done properly?

Regards,
Ole
