I'm writing a program which runs in user context and opens and writes into a
handler file exported by click in kernel mode.
I'm having problems in opening that file:
int fd_links;
fd_links=open("/click/element/handler", O_WRONLY | O_APPEND);
The open call returns -1, and the error is "Permission denied".
The program runs with root privileges (at least I think so, it is a olsrd
plugin).
Do you have any hints? I tried other flags, but I always get that error.
