Signal from kernel space to user space

[Mai Daftedar]

Hi everyone
   Im still new to the kernel development world :)and  I was wondering
what functions I can use in the kernel space for a signal to be sent
to the userspace
I tryed a number of examples I found after I did some googling that
used the API "send_sig_info" however nothing worked :(


Any help would be appreciated
Can you please CC me in the reply to this mail
Thanks
Mai
