Displaying a message on terminal

roland_andrey · 01-10-2005, 04:28 PM

I am trying to write a system call which needs to print a message on terminal of every logged on user. printk writes to /var/log/messages, panic does the thing but locks the system. what should i use?

Thanks for the help

echo whatever you want | wall

That's how I use it...

Sorry Chris that was my foolness. I didnt make the thing clear. I am writing kernel code /usr/src/linux/kernel/user.c and that is where i wish to use the message thing.

Thanks again
