Hi, You can create a proc entry, or a device entry through which you can register the pid of the process to which you want to send the signal. some thing like /proc/reg_pid -------------------------------- echo <your pid> > /proc/reg_pid -------------------------------- In the kernel write a handler for the proc entry which will store the pid is some place, lets say a variable. And whenever necessary just send the signal using the kill_proc to this pid. Hope this helps Regards KK On Tue, 2003-11-25 at 23:44, Juergen Oberhofer wrote: > hm the thing is, that the module doesn't know the pid of the user process... > I would need a function, equivalent to the > int kill(pid_t pid, int sig); > function, defined in signal.h.
