No, it isn't - iocp's are not powerful enough to emulate the posix event api. > http://www.eggheadcafe.com/software/aspnet/32292639/integrate-windows-io-com.aspx > seems to explain how. the problem is that the famous "passing in a zero byte buffer" trick a) isn't supported by the windows api and b) often fails in practise. besides, performance with a medium number of file handles is likely to be much better with select (or the new wsapoll). with a higher number of handles, iocps would (if possible) perform better. the job of libev is to support the posix model on windows, so programs can be ported well, at a performance cost because of the extremely braindamaged and windows api. the goal is to be compatible, not to have windows-specific hacks that complicate libev user programs. besides, there is no point in wasting ten times the amount of code in getting marginally better performance for that platform. > Twould be nice to have a mechanism in win32 to overcome the FD_SETSIZE > limitation. There is, it's called #define? If you had read the libev documentation, as you were told a number of times already, you'd know about that. > Here's to wishing :) > Thoughts?
