c++ 創建 socket server

#include <sys/types.h>
#include <sys/socket.h>
#include <arpa/inet.h>

        int ss = -1;
	ss = socket(AF_INET,SOCK_STREAM,0); //獲得句柄
	if(ss < 0){
		fprintf(stderr,"socket create error\n");
		return false;
	}
	server_fd = ss;
	sockaddr_in server_addr;
	server_addr.sin_family = AF_INET; //協議類型
	server_addr.sin_addr.s_addr = htonl(INADDR_ANY);//ip地址
	server_addr.sin_port = htons(server_port);//端口號
	int ret =  bind(ss,(sockaddr*)&server_addr,sizeof(server_addr)); //綁定地址與端口
	if(ret < 0){
		fprintf(stderr,"error in bind\n");
		return false;
	}
	ret = listen(ss,max_wait_num);//開始監聽
	if(ret < 0){
		fprintf(stderr,"error in listen\n" );
		return false;
	}

int sc = accept(ss,(sockaddr*)&from,&len);
fprintf(stderr, "get one connection:[%d]\n", sc);
