Displaying message on FC1

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

Actually, a simple way to do this is make a bash script with this:
#!/bin/bash
echo "message" > /dev/ttys_you_want
#be sure to list the ttys in a space seperated list eg. /dev/ttyx /dev/ttya...

Sorry 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. Does that still works?, cauz it generated an error.

Thanks again
