Libev is modelled (very losely) after libevent and the Event perl |
| 13 |
module, but is faster, scales better and is more correct, and also more |
| 14 |
featureful. And also smaller. Yay. |
| 15 |
|
| 16 |
Some of the specialties of libev not commonly found elsewhere are: |
| 17 |
|
| 18 |
- extensive and detailed, readable documentation (not doxygen garbage). |
| 19 |
- fully supports fork, can detect fork in various ways and automatically |
| 20 |
re-arms kernel mechanisms that do not support fork. |
| 21 |
- highly optimised select, poll, epoll, kqueue and event ports backends. |
| 22 |
- filesystem object (path) watching (with optional linux inotify support). |
| 23 |
- wallclock-based times (using absolute time, cron-like). |
| 24 |
- relative timers/timeouts (handle time jumps). |
| 25 |
- fast intra-thread communication between multiple |
| 26 |
event loops (with optional fast linux eventfd backend). |
| 27 |
- extremely easy to embed. |
| 28 |
- very small codebase, no bloated library. |
| 29 |
- fully extensible by being able to plug into the event loop, |
| 30 |
integrate other event loops, integrate other event loop users. |
| 31 |
- very little memory use (small watchers, small event loop data). |
| 32 |
- optional C++ interface allowing method and function callbacks |
| 33 |
at no extra memory or runtime overhead. |
| 34 |
- optional Perl interface with similar characteristics (capable |
| 35 |
of running Glib/Gtk2 on libev, interfaces with Net::SNMP and |
| 36 |
libadns). |
| 37 |
- support for other languages (multiple C++ interfaces, D, Ruby, |
| 38 |
Python) available from third-parties. |

Examples of programs that embed libev: the EV perl module, |
| 41 |
rxvt-unicode, gvpe (GNU Virtual Private Ethernet), the Deliantra MMORPG |
| 42 |
server (http://www.deliantra.net/), Rubinius (a next-generation Ruby |
| 43 |
VM), the Ebb web server, the Rev event toolkit. |
