| libev Echo Client / Server | ||
| ==== | ||
|
|
||
| A collection of simple examples for libev. | ||
|
|
||
| Please fork and contribute. | ||
|
|
||
| Usage | ||
| ==== | ||
|
|
||
| The working examples so far consist of `Unix Socket` **echo server** *and* **echo client**. | ||
|
|
||
| unix socket | ||
| ---- | ||
|
|
||
| I'm awaiting confirmation from veterans on the **libev mailing list** that this is done, in fact, *the right way*(TM). | ||
|
|
||
| These should be very easily adaptable with some very very simple cut/paste action to produce a TCP example echo server. | ||
|
|
||
| You should be able to make them and then type on the console and see that the data does go back and forth. | ||
|
|
||
| make unix-echo-server unix-echo-client | ||
|
|
||
| In terminal A: | ||
|
|
||
| ./unix-echo-server | ||
|
|
||
| Then type away in terminal B: | ||
|
|
||
| ./unix-echo-client | ||
|
|
||
| Note: Opening the client and server in reverse order won't work. | ||
|
|
||
| For testing and for reference, compatible servers written for `Node.JS` are provided. | ||
|
|
||
| udp socket | ||
| ---- | ||
|
|
||
| If I understand it correctly, it may be that This example is not actually taking | ||
| advantage of any of the features of libev. | ||
| I grabbed it from the mailing list and I think it just wraps blocking code in libev. | ||
|
|
||
| * `make`the `udp-echo` binary | ||
| * start the `udp-echo` server in one terminal | ||
| * test that you can see the open port `3333` in another | ||
| * test that you see when `udp.js` connets by the message in the first terminal | ||
|
|
||
| Expected procedure and results: | ||
|
|
||
| $ make udp-echo && ./udp-echo | ||
| cc -Wall -Werror -lev -o udp-echo udp-echo.c | ||
| udp_echo server started... | ||
|
|
||
|
|
||
| $ netstat -lau | grep 3333 | ||
| udp 0 0 *:3333 *:* | ||
|
|
||
| $ node udp.js | ||
| # this show up on the server window | ||
| udp socket has become readable | ||
|
