I recently was made aware of this thing called IOCP on windows and i began searching for more information on it but i couldn't find anything up to date (most of the examples were on codeproject almost 5 years old) and not too many guides or tutorials. Can anyone recommend any up to date resources about it in the form of online tutorials or example projects (that you wrote and can share or other open source projects) or even a book about it because if it's as good as it sounds i plan to use it extensively so i will invest in it.
Thank You.
IOCP is a feature that has been in Windows since the dark ages and has changed little in years since. As such, any samples etc. from 5+ years ago should still work pretty well today.
MSDN has some documentation on IOCP: http://msdn.microsoft.com/en-us/library/aa365198%28v=VS.85%29.aspx
Mark Russinovich also wrote up a great intro into IOCP: http://sysinternals.d4rk4.ru/Information/IoCompletionPorts.html
Mark also wrote a more thorough description of Windows' IO infrastructure in "Windows Internals" which is essential reading.
I also strongly recommend Jeffery Richter's "Windows via C/C++" which is also essential reading for anyone embarking on lower-level Windows programming.
HTH.
