History Kernel Module

[Timwe]

hey guys,

i am trying to implement a module that reads from

proc/meminfo
proc/cpuinfo

and writes it in another file in proc

i also need the current process list written in the same file, yet i couldnt go that far for now.

can i use straight good old fprintf() in classical manner? or is there a more systematic way to do it?

if you think fprintf() would satisfy, what may be the parameters?

Bad idea. The linux kernel doesn't read files. That's a user space task. In fact that are not common files but pseudo-files. Please, read these articles:

You can not use libc libraries from inside the kernel at all . Read some books about kernel programming. You can start for these articles:
