Hi, I have come up with a kernel module doing monitoring of system calls and will printk messages. Now I want to show these messages to user through an application.
I can write an application to read from file but not from "/proc/kmsg" where the printk messages are stored. So I think either there is a way to show "/proc/kmsg' or have to write the printk messages to a file then read from it.
