| |
Hi, I believe that we are advised to use copy_to_user() for converting to user space. But since this is not exported, are we supposed to export it(in ksyms.c), rebuild the kernel and then use it ? Suppose I want to write device drivers, the probability is very high that I will have it as a module and the probability is even higher that I'll have to use functions like copy_to_user/copy_from_user or the obsolete versions memcpy_tofs/memcpy_fromfs and these aren't exported. Looks like linux by nature, doesn't encourage modular devide drivers.
Am I right or am I missing something ?
Forgive me if this a stupid question.
Thanks Kesava
