error while implementing kill()

error while implementing kill()

[sounak chakraborty]

  
dear sir,
 I am unable to use the system call kill(pid,sig).I
have included the header file <signal.h>. I used it in
a module to kill a process. The module is compiling
properly but giving the following error while
inserting the module,
   unresolved symbol kill()

I am unable to track the bug here. 
kindly help me out.

I want to kill a process through the process ID inside
a module.
Is there any other approach other than using the
kill() function?

Thanks in advance,

sounak

Who says that kill() is
1) a defined function
2) is the function that does what the libc call does
3) is the function that does what you expect

As for sending signals,
it's been posted today already, see the archives.

kill_proc(pid, SIGNAL, x) is used inside the kernel to
send signals to kernel threads. It is not necessarily
the way to kill user-mode tasks. They should be
sent a fatal signal from user-mode.
