Please look at this tiny winsock code

[abdul]

I have just started learning Winsock. I have problem running the first example of winsock then just sits and listens to the port. I am using VC++ 6.0 and here is the code:


#include <winsock.h>
#include <windows.h>
WSADATA info;
WORD version = MAKEWORD(1,1);
WSAStartup(version, &info);

/* code to establish a socket
*/
SOCKET establish(unsigned short portnum)
{ char myname[256];
SOCKET s;
struct sockaddr_in sa;
struct hostent *hp;

memset(&sa, 0, sizeof(struct sockaddr_in)); /* clear our address */
gethostname(myname, sizeof(myname)); /* who are we? */
hp = gethostbyname(myname); /* get our address info */
if (hp == NULL) /* we don't exist !? */
return(INVALID_SOCKET);
sa.sin_family = hp->h_addrtype; /* this is our host address */
sa.sin_port = htons(portnum); /* this is our port number */
s = socket(AF_INET, SOCK_STREAM, 0); /* create the socket */
if (s == INVALID_SOCKET)
return INVALID_SOCKET;

/* bind the socket to the internet address */
if (bind(s, (struct sockaddr *)&sa, sizeof(struct sockaddr_in)) ==
SOCKET_ERROR) {
closesocket(s);
return(INVALID_SOCKET);
}
listen(s, 3); /* max # of queued connects */
cout<<myname;
return(s);

WSACleanup();
}



The errors that I get are here:

Can you please tell me what I am doing wrong here.

I am now going to sleep and I will check tomorrow : (
