Does anyone know where I can get up to date information about the state on Kernel support for aio on the latest Linux Kernel?. Google searches bring up web pages that may be hopelessly out of date.
Edit:
More specifically, I am interested in non-file related descriptors like pipes and sockets. Stuff on the web indicate that there is no support, is this still the case?
Edit2:
What I am looking for is something similar to Windows OVERLAPPED IO
AIO support has been included in the linux kernel proper. That’s why the first hit on Google only offers patches to the 2.4 Linux kernel. In 2.6 and 3.0 it’s already in there.
If you checkout the Linux kernel source code, it’s at fs/aio.c
There’s some documentation in the GNU libc manual, but be advised that aio is not possible for all types of Linux file descriptors. Most of the general “how to” documentation is dated around 2006, which is appropriate since that’s when AIO in Linux was making the headlines.
Note that the POSIX.1b and Unix98 standards haven’t changed, so can you be a bit specific as to the nature of the “out-of-date”ness of the examples?
