Create a Unix domain socket in Go using net.ListenUnix with a file path and accept connections via AcceptUnix.

Use net.ListenUnix to create a listener on a Unix domain socket path, then accept connections with Accept.

package main

import (
	"fmt"
	"net"
)

func main() {
	listener, err := net.ListenUnix("unix", &net.UnixAddr{Net: "unix", Name: "/tmp/my.sock"})
	if err != nil {
		panic(err)
	}
	defer listener.Close()

	conn, err := listener.AcceptUnix()
	if err != nil {
		panic(err)
	}
	defer conn.Close()

	fmt.Println("Connected")
}
