193 | <p>This is your standard select(2) backend. Not <i>completely</i> standard, as |
|
|
194 | libev tries to roll its own fd_set with no limits on the number of fds, |
|
|
195 | but if that fails, expect a fairly low limit on the number of fds when |
|
|
196 | using this backend. It doesn't scale too well (O(highest_fd)), but its usually |
|
|
197 | the fastest backend for a low number of fds.</p> |

203 | number of fds you can use (except it will slow down considerably with a |

197 | backends will be tried (in the reverse order as given here). If one are |

198 | specified, any backend will do.</p> |
208 | <p>For few fds, this backend is a bit little slower than poll and select, |
|
|
209 | but it scales phenomenally better. While poll and select usually scale like |
|
|
210 | O(total_fds) where n is the total number of fds (or the highest fd), epoll scales |
|
|
211 | either O(1) or O(active_fds).</p> |
|
|
212 | <p>While stopping and starting an I/O watcher in the same iteration will |
|
|
213 | result in some caching, there is still a syscall per such incident |
|
|
214 | (because the fd could point to a different file description now), so its |
|
|
215 | best to avoid that. Also, dup()ed file descriptors might not work very |
|

216 | well if you register events for both fds.</p> |

218 | <dt><code>EVMETHOD_KQUEUE</code> (value 8, most BSD clones)</dt> |

219 | <dd> |
|
|
220 | <p>Kqueue deserves special mention, as at the time of this writing, it |
|
|
221 | was broken on all BSDs except NetBSD (usually it doesn't work with |
|
|
222 | anything but sockets and pipes, except on Darwin, where of course its |
|
|
223 | completely useless). For this reason its not being "autodetected" unless |
|
|
224 | you explicitly specify the flags (i.e. you don't use EVFLAG_AUTO).</p> |
|
|
225 | <p>It scales in the same way as the epoll backend, but the interface to the |
|
|
226 | kernel is more efficient (which says nothing about its actual speed, of |
|
|
227 | course). While starting and stopping an I/O watcher does not cause an |
|
|
228 | extra syscall as with epoll, it still adds up to four event changes per |
|
|
229 | incident, so its best to avoid that.</p> |

838 | <p>Libev offers a compatibility emulation layer for libevent. It cannot |
|
|
839 | emulate the internals of libevent, so here are some usage hints:</p> |
|
|
840 | <dl> |
|
|
841 | <dt>* Use it by including <event.h>, as usual.</dt> |
|
|
842 | <dt>* The following members are fully supported: ev_base, ev_callback, |
|
|
843 | ev_arg, ev_fd, ev_res, ev_events.</dt> |
|
|
844 | <dt>* Avoid using ev_flags and the EVLIST_*-macros, while it is |
|
|
845 | maintained by libev, it does not work exactly the same way as in libevent (consider |
|
|
846 | it a private API).</dt> |
|
|
847 | <dt>* Priorities are not currently supported. Initialising priorities |
|
|
848 | will fail and all watchers will have the same priority, even though there |
|
|
849 | is an ev_pri field.</dt> |
|
|
850 | <dt>* Other members are not supported.</dt> |
|
|
851 | <dt>* The libev emulation is <i>not</i> ABI compatible to libevent, you need |
|
|
852 | to use the libev header file and library.</dt> |
