net

The current net TCP surface is blocking-style and built around TcpListener / TcpStream value types.

TCP Listener

let listener = TcpListener("127.0.0.1", 8080)
if listener.fd < 0 {
    $println("listen failed")
}

let stream = listener.accept()
stream.close()
listener.close()

TCP Stream

let stream = TcpStream("127.0.0.1", 8080)
if stream.fd >= 0 {
    stream.writeStr("hello")
    stream.close()
}

Current Surface Notes

• TcpListener(ip, port) constructs a listener.
• accept() returns a TcpStream.
• TcpStream(ip, port) constructs a connected stream.
• read(buf: *u8, len: i32): i64
• write(data: *u8, len: i32): i64
• writeStr(s: string): i64
• close() closes the socket.

This page intentionally documents the current tested exported surface, not an aspirational async socket wrapper.
