Hi, How can I use memcoyp in memcpy? I try #include stdio.h and string.h, but .h fails to include during compilation. Can you please help me? Thank you.

stdio is a libc invention, only used in userspace. As such, you can't call anything in a shared library from within kernel code (although there are similarly named routines for many things).

That's because stdio.h is a C library header. You can't use the C library in the kernel. You should actually be able to include string.h, but you need the kernel version, which lives in include/linux/string.h. The kernel provides a few of the functions usually provided by the C library. Things like memcpy() and memset() exist. printf() doesn't, but there is an sprintf(), ... Kristof

Hi, stdio.h and string.h are glibc header files (userspace)... Kernelspace is another thing. Try to include "linux/string.h" -- Augusto Mecking Caringi
