send_sig_info() -- struct siginfo??

[<samandbuffy@yahoo.com>]

Hey guys,

I'm still trying to figure out how to send a signal to
a process.

 send_sig_info(int, struct siginfo *, struct
task_struct*) is used.

1. the INT is the PID of the target process
2. I can find the task_struct* by using the function  
  find_task_by_Pid()

But, what is siginfo?  I looked at the structure, but
I still couldn't make sense of it.  If I know the PID
of the target process, how can I fill in the siginfo
structure in order to send a signal out?

ANy help would be greatly appreciated!!

THanks,

Sam
