Hello, I want to get the information of fd (file descriptor) of all the processes in the system. I mean that the list of file names which is currently opened by a process is needed. I think I can get it by checking the /proc/<PID>/fd directory in the user level. But what I want is to get it in kernel level (kernel module) I think there must some data structures that keep the list of working processes in the system and also data strcutures that keep file descriptors which is currently opened and pointing a file. Please help me if you know something. Thank you verh much. - Seongsu -- Kernelnewbies: Help each other learn about the Linux kernel.
