example CLIENT code that connects to a TCP socket & sends GOB-encoded data

tcpgobclient.go

package main

// use this with tcpgobserver.go

import (
	"encoding/gob"
	"fmt"
	"log"
	"net"
)

type P struct {
	M, N int64
}

func main() {
	fmt.Println("start client")
	conn, err := net.Dial("tcp", "localhost:7743")
	if err != nil {
		log.Fatal("Connection error", err)
	}
	encoder := gob.NewEncoder(conn)
	p := &P{8192, 4096}
	encoder.Encode(p)
	conn.Close()
	fmt.Println("done")
}
