POE::XS::Loop::EPoll - an XS implementation of POE::Loop, using Linux` epoll(2).


  use POE::Kernel { loop => 'POE::XS::Loop::EPoll' };


This class is an implementation of the abstract POE::Loop interface written in C using the Linux epoll(2) family of system calls.

Signals are left to POE::Loop::PerlSignals.

The epoll_ctl() call returns an error when you attempt to poll regular files, POE::XS::Loop::EPoll emulate's poll(2)'s behaviour with regular files under Linux - ie. they're always readable/writeable.

If you see an error:

  POE::XS::Loop::EPoll hasn't been initialized correctly

then the loop hasn't been loaded correctly, in POE <= 1.287 the following:

  # this doesn't work
  use POE qw(XS::Loop::EPoll);

will not load the loop correctly, you will need to do:

  use POE::Kernel { loop => 'POE::XS::Loop::EPoll' };
  use POE;


POE, POE::Loop, POE::XS::Loop::Poll.


Relies upon small fd numbers, but then a lot of code does.

POE::XS::Loop::EPoll is licensed under the same terms as Perl itself.
