我常用的socket 框架

 

  1.  Server端
     1 int main()
     2 {
     3     WORD sockVersion;
     4     WSADATA wsaData;
     5     int rVal;
     6 
     7     sockVersion = MAKEWORD(1,1);
     8     //start dll
     9      WSAStartup(sockVersion, &wsaData);
    10 
    11     //create socket
    12      SOCKET s = socket(PF_INET, SOCK_STREAM, IPPROTO_TCP);
    13 
    14     if(s == INVALID_SOCKET)
    15     {
    16         socketError("Failed socket()");
    17         WSACleanup();
    18         return SERVER_SOCKET_ERROR;
    19     }
    20 
    21     //fill in sockaddr_in struct 
    22 
    23     SOCKADDR_IN sin;
    24     sin.sin_family = PF_INET;
    25     sin.sin_port = htons(8888);
    26     sin.sin_addr.s_addr = INADDR_ANY;
    27 
    28     //bind the socket
    29     rVal = bind(s, (LPSOCKADDR)&sin, sizeof(sin));
    30     if(rVal == SOCKET_ERROR)
    31     {
    32         socketError("Failed bind()");
    33         WSACleanup();
    34         return SERVER_SOCKET_ERROR;
    35     }
    36 
    37     //get socket to listen 
    38     rVal = listen(s, 2);
    39     if(rVal == SOCKET_ERROR)
    40     {
    41         socketError("Failed listen()");
    42         WSACleanup();
    43         return SERVER_SOCKET_ERROR;
    44     }
    45 
    46     //wait for a client
    47     SOCKET client;
    48 
    49     client = accept(s, NULL, NULL);
    50 
    51     if(client == INVALID_SOCKET)
    52     {
    53         socketError("Failed accept()");
    54         WSACleanup();
    55         return SERVER_SOCKET_ERROR;
    56     }
    57     printf("client ok\n");
    58     char buff[512] = {0};
    59     //while(1)
    60     //{
    61     getchar();
    62         recv(client, buff, 512, 0 );
    63         printf("%s\n",buff);
    64         ZeroMemory(buff, 512);
    65     //}
    66     //close process
    67     closesocket(client);
    68     closesocket(s);
    69 
    70     WSACleanup();
    71 
    72     return SOCKET_OK;
    73 }
