70EV can use various backends with various portability issue. The select
71backend is the most portable and makes for a good fallback, but it can be
72limited to a low number of file descriptors and/or might not compile. If
73you have problems with compiling ev_select.c, you might try to play around
74with disabling it here, or forcing it to use the fd_set provided by your
75OS, via the next question. I highly recommend keeping it in.

87The select backend can operate in two modes. One uses the system-provided
88fd_set and is usually limited to 1024 file descriptors (64 on windows),
89the other requires your header files to define NFDBITS and declare a
90suitable fd_mask type. If you run into problems compiling ev_select.c, you
91can try forcing the use of the system fd_set here.

107The second very portable backend is poll(2). It does not exist on windows
108and various versions of Mac OS X (and on the other versions it simply
109doesn't work), but works basically everywhere else. It is recommended to use
110the default here unless you run into compile problems in ev_poll.c.

121Select and poll make it hard to write efficient servers, especially if the
122number of active connections is much lower than the watched ones. GNU/Linux
123systems have a more scalable method called "epoll", which EV can use. For
124this to work, both your kernel and glibc have to support epoll, but if you
125can compile it, the detection will be done at runtime, and EV will safely
126fall back to using select when epoll isn't available. If unsure, accept
127the default.

138Similarly to the epoll backend above, EV can take advantage of kqueue on
139many BSD systems. Support for kqueue will be detected at runtime, with a
140safe fallback to other methods when it cannot be used.
141
142Note that kqueue is broken on most operating systems, so it defaults to
143'n' on everything but netbsd. Here is what we know:
144
145NetBSD: working in at least 3.1. Yeah! :)
146FreeBSD: broken on at least 6.2-STABLE,
147 sockets and pipes *might* work, ptys definitely don't.
148OpenBSD: reports indicate that it likely doesn't work
149 (similar problems as on FreeBSD).
150OS X: completely, utterly broken on at least <= 10.5.
