简单socket连接，tcp，备用

SOCKET Connect(CHAR* lpText, USHORT uPort){SOCKET s;s = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);if (s != INVALID_SOCKET){CHAR szIp[32] = {0};sockaddr_in sa;if (inet_addr(lpText) == INADDR_NONE){if (struct hostent *hp = gethostbyname(lpText)){in_addr ia;CopyMemory(&ia, hp->h_addr, hp->h_length);lstrcpyA(szIp, inet_ntoa(ia));}}else{lstrcpyA(szIp, lpText);}sa.sin_family = AF_INET;sa.sin_port = htons(uPort);sa.sin_addr.s_addr = inet_addr(szIp);if (connect(s, (sockaddr*)&sa, sizeof(sa)) != 0){closesocket(s);s = INVALID_SOCKET;}}return s;}
