socket通訊實現

為了實現socket的通訊驗證，寫了乙個簡單的客服端向伺服器端通訊的**

伺服器端：

1、版本驗證

word wversionrequested=

makeword(2
,2);
wsadata result;
int err =
wsastartup
(wversionrequested,
&result);if
(err !=0)
if(lobyte
(result.wversion)!=2
||hibyte
(result.wversion)!=2
)

socket ser_sock =

socket
(af_inet, sock_stream, ipproto_tcp);if
(invalid_socket == ser_sock)

struct sockaddr_in ser_addr;

memset
(&ser_addr,0,
sizeof
(ser_addr));
ser_addr.sin_family = af_inet;
ser_addr.sin_addr.s_addr =
inet_addr
("192.168.1.104");
ser_addr.sin_port =
htons
(10000);
//埠轉為大端位元組序
int back=
bind
(ser_sock,
(sockaddr*
)&ser_addr,
sizeof
(ser_addr));
if(socket_error == back)

//監聽

int re =
listen
(ser_sock,10)
;if(socket_error == re)
//接收
printf
("等待連線。。。。\n");
socket jie =
accept
(ser_sock,
null
,null);
if(invalid_socket == jie)
printf
("連線成功！\n"
);

char buff[

1024];
while(1
)}

幾乎流程與上述相同只是不需要繫結、監聽，接受步驟，直接改為連線和通訊

**實現：

word wversionrequested =

makeword(2
,2);
wsadata result;
int err =
wsastartup
(wversionrequested,
&result);if
(err !=0)
if(lobyte
(result.wversion)!=2
||hibyte
(result.wversion)!=2
)//生成套接字
socket cli_sock =
socket
(af_inet, sock_stream, ipproto_tcp);if
(invalid_socket == cli_sock)
//裝置資訊
struct sockaddr_in ser_addr;
memset
(&ser_addr,0,
sizeof
(ser_addr));
ser_addr.sin_family = af_inet;
ser_addr.sin_addr.s_addr =
inet_addr
("192.168.1.104");
ser_addr.sin_port =
htons
(10000);
//埠轉為大端位元組序
//連線
int co =
connect
(cli_sock,
(sockaddr*
)&ser_addr,
sizeof
(ser_addr));
printf
("正在建立連線。。。。。\n");
if(socket_error == co)
printf
("連線成功！\n");
//通訊
