Hi Igor R and Yang Acer,

I found from where you pointed by grepping

$ grep -r "EPOLLET" ./
./boost/asio/detail/impl/epoll_reactor.ipp:  ev.events = EPOLLIN | EPOLLERR
| EPOLLET;
./boost/asio/detail/impl/epoll_reactor.ipp:    ev.events = EPOLLIN |
EPOLLERR | EPOLLET;
./boost/asio/detail/impl/epoll_reactor.ipp:  ev.events = EPOLLIN | EPOLLERR
| EPOLLHUP | EPOLLPRI | EPOLLET;
./boost/asio/detail/impl/epoll_reactor.ipp:  ev.events = EPOLLIN | EPOLLERR
| EPOLLHUP | EPOLLPRI | EPOLLET;
./boost/asio/detail/impl/epoll_reactor.ipp:  ev.events = EPOLLIN | EPOLLERR
| EPOLLET;

$ grep -r "EPOLLIN" ./
./boost/asio/detail/impl/epoll_reactor.ipp:  ev.events = EPOLLIN | EPOLLERR
| EPOLLET;
./boost/asio/detail/impl/epoll_reactor.ipp:    ev.events = EPOLLIN |
EPOLLERR;
./boost/asio/detail/impl/epoll_reactor.ipp:    ev.events = EPOLLIN |
EPOLLERR | EPOLLET;
./boost/asio/detail/impl/epoll_reactor.ipp:      ev.events = EPOLLIN |
EPOLLERR;
./boost/asio/detail/impl/epoll_reactor.ipp:  ev.events = EPOLLIN | EPOLLERR
| EPOLLHUP | EPOLLPRI | EPOLLET;
./boost/asio/detail/impl/epoll_reactor.ipp:  ev.events = EPOLLIN | EPOLLERR
| EPOLLHUP | EPOLLPRI | EPOLLET;
./boost/asio/detail/impl/epoll_reactor.ipp:  ev.events = EPOLLIN | EPOLLERR
| EPOLLET;
./boost/asio/detail/impl/epoll_reactor.ipp:  static const int flag[max_ops]
= { EPOLLIN, EPOLLOUT, EPOLLPRI };

So boost uses edge-triggered manner of epoll
And I learned a little of the purpose of ipp. Boost developpers are
template gurus!

Thank you very much.

Sincerely
Journeyer
