по мсдну написал следуйщее:
сервер:

int BufLen = 1024;
struct sockaddr_in SenderAddr;
int SenderAddrSize = sizeof(SenderAddr);

RecvSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
peer.sin_family = AF_INET;
peer.sin_addr.s_addr = inet_addr("127.0.0.1");
peer.sin_port = htons(27015);(INADDR_ANY);

if (listen( RecvSocket, 1 ) == SOCKET_ERROR) {

closesocket( RecvSocket);
WSACleanup();
return 1;
}

recv(RecvSocket,

for(int i = 0; i<strlen(RecvBuf); i++)

когда вывожу строку, появляется абракадабра.
что делать? |
