copy_to_user

[idog2k]

Hi,
I am trying to use the function copy_to_user but after I do
make bzImage

I get a link error:

kernel/kernel.o (somthing...) undefined reference to copy_to_user

what should I do to solve this problem?

thanks

hai,
you can include the header file " #include <asm/uacces.h>"

What these functions(copy_to_user and copy_from_user) are doing?kernal space to user space and user space to kernel space conversion.Really they are doing some memory conversion?
