You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: main.go
    path of file: ./repos/learning/golang/source_code/Go语言核心编程代码/chatsys/server/main
    
    the code of the file until where you have to start completion: package main
import (
	"fmt"
	"net"
	"time"
	"go_code/chatsys/server/model"
)



func initUserDao() {
	//说明pool 是一个全
    
func proccess(conn net.Conn) {

	//defer conn.Close()
	//创建一个client,相当于一个控制器
	cp := &ClientProcessor{
		conn: conn,
	}
	//让client进行处理，其实主要是让client将不同的
	//请求，分配给不同的处理器文件去处理.
	err := cp.Process()
	if err != nil {
		fmt.Println("client process failed err= ", err)
		return
	}

}
