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.
