Re: [Libevent-users] FD_SETSIZE - max connections in Windows - help!

[lau stephen <liusifan@xxxxxxxxx>]

This package is built success with VC6 or VS2003 on Windows XP platform.
It need to use libevent-1.4.7-stable-iocp-1\WIN32-Prj\libevent.dsw .

Which libevent version do you use currently?
I should port iocp related things to that version.
