POSIX optionally offers support for a monotonic clock source. EV |

can take advantage of this clock source to detect time jumps |
40 |

reliably. Unfortunately, some systems are bound to be broken, so you can |
41 |

disable this here: you can completely disable the detection and use of |
42 |

the monotonic clock by answering 'n' here. Support for this clock type |

will otherwise be autodetected at both compile- and runtime. |

POSIX optionally offers support for a (potentially) high-resolution |

realtime clock interface. In a good implementation, using it is faster |

than the normal method of using gettimeofday. Unfortunately, this option |

EV can use various backends with various portability issue. The select |
71 |
|
|
backend is the most portable and makes for a good fallback, but it can be |
72 |
root |
1.22 |
limited to a low number of file descriptors and/or might not compile. If |
73 |
|
|
you have problems with compiling ev_select.c, you might try to play around |
74 |
root |
1.19 |
with disabling it here, or forcing it to use the fd_set provided by your |
75 |
|
|
OS, via the next question. I highly recommend keeping it in. |

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

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

EV by default uses select, which makes it hard to write efficient servers, |
122 |
root |
1.22 |
especially if the number of active connections is much lower than the open |
123 |
root |
1.15 |
ones. GNU/Linux systems have a more scalable method called "epoll", which |
124 |
|
|
EV can use. For this to work, both your kernel and glibc have to support |
125 |
|
|
epoll, but if you can compile it, the detection will be done at runtime, |
126 |
|
|
and EV will safely fall back to using select when epoll isn't available. |
127 |
|
|
If unsure, accept the default. |

Similarly to the epoll backend above, EV can take advantage of kqueue |
139 |
|
|
on many BSD systems (it seems to be broken on Mac OS X though, but what |
140 |
|
|
isn't broken on that shoddy platform... ah yes, the cash gushing by apple, |
141 |

selling defective software works perfectly there). Support for kqueue will |

EV needs the functions pthread_atfork and clock_gettime. On most systems |

root |

you need some special libraries for this (such as -lrt and -lpthread). You |

default. |
