You can't call sys_* functions from kernel as they are not exported and only for system calls. For Accessing File from kernel space (although its not a good thing) you can see this thread (http://mail.nl.linux.org/kernelnewbies/2005-10/msg00249.html) ! > or is there other method for me to get connection information in kernel > There might be some other way of getting connection information in kernel, but I can't tell the way of doing this as I havn't worked on network side of kernel :) -- Fawad Lateef -- Kernelnewbies: Help each other learn about the Linux kernel.
