You can do this from within the module_init() handler only:
module_init_handler(...)
{
mm_segment_t old_fs;
old_fs = set_fs(KERNEL_DS);
sys_write(1, "foo\n", 4);
set_fs(old_fs);
...
}
The text comes out on modprobe's standard output.
Don't tell anyone I told you this.

Please consult the manual for dmesg and syslog. And please have a look at a good Linux kernel book. This will help you understand the kernel and will answer most of your questions. -- Martin Waitz signature.asc Description: Digital signature

Hi, I have created a dummy module for learning device driver in linux. I want to redirect the standard output of printk to my xterm. But by default it is redirected to tty.
