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.

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

138Similarly to the epoll backend above, EV can take advantage of kqueue
139on many BSD systems (it seems to be broken on Mac OS X though, but what
140isn't broken on that shoddy platform... ah yes, the cash gushing by apple,
141selling defective software works perfectly there). Support for kqueue will
142be detected at runtime, with a safe fallback to other methods when it
143cannot be used.
