samba - Aug 1998 - samba pidfile

Hi all, 
sorry about the samba newbie question, but..
where is pidfile for the smbd processes  that are currently running?
I know smbstatus, but it reports the number of current connections ( I
think) which is one less than a ps -ef smbd (or equivalent) outputs.
Basically, I am looking at a script to kill all smbd and the nmbd
processes. Unfortunately, O/S is solaris, and I don't have the linux
'killall' command (well, I do, but I do not want to kill the entire
system.

Thanks for any tips,

Ian
