wouldn't this be easier in user space using "ps H" then one of two options happens depending on the use of fork and other issues (making the question hard to answer as stated) either A: they will all have the same PID or B:they will all have varying PIDs in the later case you could use looks for all PIDs sharing the same ancestor PPID (depending on how far down you are in the fork list) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
