libev Echo Client / Server
A collection of simple examples for libev.
Please fork and contribute.
The working examples so far consist of
Unix Socket echo server and echo client.
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:
Then type away in terminal B:
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.
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.
- start the
udp-echoserver in one terminal
- test that you can see the open port
- test that you see when
udp.jsconnets 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
sudo apt-get install libev libev-dev
