The following reply was made to PR kern/34017; it has been noted by GNATS. From: k Macy <kip_macy@yahoo.com> To: Garrett Wollman <wollman@khavrinen.lcs.mit.edu> Cc: freebsd-gnats-submit@FreeBSD.ORG Subject: Re: kern/34017: The siginfo_t passed to the signal handling routine is not filled out for AIO Date: Fri, 18 Jan 2002 12:53:00 -0800 (PST) Is using SIGEV_SIGNAL with AIO to deliver a SIGIO on completion fall under the heading of real time signals? If that is the case, SA_SIGINFO is not useful, because it gives you the same information in the (siginfo_t *info) as the (int code) would contain. It is at least a bug in the documentation. In the man page it should say that the siginfo_t does not get filled out, and that SA_SIGINFO is just there for some level of posix compatibility. If you're certain of this, this can be reclassified as an RFE, and I'll submit a docs bug. --- Garrett Wollman <wollman@khavrinen.lcs.mit.edu> wrote: > <<On Thu, 17 Jan 2002 21:59:08 -0800 (PST), Kip Macy > <kip@eventdriven.org> said: > > > One can, when using AIO, enable a signal to be > delivered on completion. > > The siginfo_t passed to the signal handling > routine that gets called on > > completion is supposed to have a reference to the > sigev_value that is > > set when the aio_* operation is dispatched.
