Thread: winsock

hi i found this code at
Johnnies winsock tutorial

Code:

#define NETWORK_ERROR -1
#define NETWORK_OK     0

	int nret;

	sockVersion = MAKEWORD(1, 1);			// We'd like Winsock version 1.1


	// We begin by initializing Winsock
	WSAStartup(sockVersion, &wsaData);


	// Next, create the listening socket
	SOCKET listeningSocket;

	listeningSocket = socket(AF_INET,		// Go over TCP/IP
			         SOCK_STREAM,   	// This is a stream-oriented socket
				 IPPROTO_TCP);		// Use TCP rather than UDP

	if (listeningSocket == INVALID_SOCKET) {

	}


	// Use a SOCKADDR_IN struct to fill in address information

	serverInfo.sin_family = AF_INET;
	serverInfo.sin_addr.s_addr = INADDR_ANY;         
	// = inet_addr("192.168.0.118");
	// Since this socket is listening for connections,
							// any local address will do
	serverInfo.sin_port = htons(888);		// Convert integer 8888 to network-byte order

	// Bind the socket to our local server address
	nret = bind(listeningSocket, (LPSOCKADDR)&serverInfo, sizeof(struct sockaddr_in));

	if (nret == SOCKET_ERROR) {

		WSACleanup();

	}


	// Make the socket listen

		nret = WSAGetLastError();

		WSACleanup();
		return NETWORK_ERROR;
	}


	// Send and receive from the client, and finally,
	closesocket(theClient);
	closesocket(listeningSocket);


	// Shutdown Winsock
	WSACleanup();
	return NETWORK_OK;
}


void ReportError(int errorCode, const char *whichFunc) {
   char errorMsg[92];					// Declare a buffer to hold
							// the generated error message
   
   ZeroMemory(errorMsg, 92);				// Automatically NULL-terminate the string

   // The following line copies the phrase, whichFunc string, and integer errorCode into the buffer
   sprintf(errorMsg, "Call to %s returned error %d!", (char *)whichFunc, errorCode);

   MessageBox(NULL, errorMsg, "socketIndication", MB_OK);
}

i get an error that says call to bind() returned error 1048
1048 is the error# that u can find



here

can anyone see whats wrong?

btw what i would want to do is an app that sends a text message when u connect to it
