Be sure U called
WSADATA wSaData;
WsaStartup( 0x201/*sock version*/, &wSaData);

int bind(
    SOCKET                     s,
    const struct sockaddr FAR* name,
    int                        namelen
);




The first parameter, s, is the socket on which you want to wait for client connections. The second parameter is of type struct sockaddr, which is simply a generic buffer. You must actually fill out an address buffer specific to the protocol you are using and cast that as a struct sockaddr when calling bind. The Winsock header file defines the type SOCKADDR as struct sockaddr. We’ll use this type throughout the chapter for brevity. The third parameter is simply the size of the protocol-specific address structure being passed. For example, the following code illustrates how this is done on a TCP connection:

SOCKET               s;    
struct sockaddr_in   tcpaddr;
int                  port = 5150;

 s = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);

tcpaddr.sin_family = AF_INET;
tcpaddr.sin_port = htons(port);    
tcpaddr.sin_addr.s_addr = htonl(INADDR_ANY);

bind(s, (SOCKADDR *)&tcpaddr, sizeof(tcpaddr));
