Queue a task to a taskqueue. Behind the scenes that will invoke a swi_add if you use the taskqueue_swi queue. However, given that you want to do some rather complicated work, you'd be better off creating a dedicated taskqueue thread and queueing tasks off to it I think. -- John Baldwin <[EMAIL PROTECTED]> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
