Networking newb problems (how to accept clients in a nonblocking way)

I want to have an (ideally) single threaded server, that can accept clients without blocking. Is there a way to check if a client wants to connect, or am I forced to go multithreaded?
Same question for reading what a client is sending btw

Hi! These might be promising solutions to explore:

  1. libxev – cross-platform event loop.

  2. http.zig – the only HTTP server in Zig that has non-blocking support (Unix-only).

If anyone knows how to please tell me :sob:
Where is my streamserver

I genuinely cant manage to read this anytype magic
Where is this “xev” defined?

It’s defined for you from one of these based on your OS. See if you can figure out how to set up a TCP client/server from this benchmark. I still couldn’t quite do that, yet :sweat_smile:

Oh sorry, the way I phrased that was missleading. I am doing this for a school project so I dont wanna use any libs except std. (Also to keep it relatively simple)

I was asking if you (or someone else for that matter) knows how to make a server with std.net master.
(Ideally but obv optionally with code samples)

The tests for std.net are really good sample code. That link goes straight to the test for a simple TCP serving scenario.

If you want to have a single threaded server, you can use std.io.poll:
zig/lib/std/io.zig at 5c0766b6c8f1aea18815206e0698953a35384a21 · ziglang/zig · GitHub.

For an example see zig/lib/std/child_process.zig at 5c0766b6c8f1aea18815206e0698953a35384a21 · ziglang/zig · GitHub.

An alternative is to use directly epoll, poll or select, depending on the OS you are using.

Thank you, I will take a look at this!

epoll based example
When client connects, this function is invoked by the engine.
