72 | EV can use various backends with various portability issue. The select |
|
|
73 | backend is the most portable and makes for a good fallback, but it can be |
|
|
74 | limited to a low number of file descriptors and/or might not compile. If |
|
|
75 | you have problems with compiling ev_select.c, you might try to play around |

89 | The select backend can operate in two modes. One uses the system-provided |
|
|
90 | fd_set and is usually limited to 1024 file descriptors (64 on windows), |
|
|
91 | the other requires your header files to define NFDBITS and declare a |

92 | suitable fd_mask type. If you run into problems compiling ev_select.c, you |

123 | Select and poll make it hard to write efficient servers, especially if the |
|
|
124 | number of active connections is much lower than the watched ones. GNU/Linux |
|
|
125 | systems have a more scalable method called "epoll", which EV can use. For |
|
|
126 | this to work, both your kernel and glibc have to support epoll, but if you |
|
|
127 | can compile it, the detection will be done at runtime, and EV will safely |
|

128 | fall back to using select when epoll isn't available. If unsure, accept |
