Not really. Files in /proc are not real, they are magically created on the fly by a registered read routine for a given procfs entry - writing to a file in /proc results in data being passed to a write procfs routine. So you can pass some data in to the kernel that way but you can't treat it like a real filesystem. > can same file be able to read by kernel in its actual > kernel execution? I hope the above makes it clear that the files are not real so the handling is all done by the kernel on each access. Jon. -- Kernelnewbies: Help each other learn about the Linux kernel.
