关于RAW SOCKET的问题

[breakpointer]

if ((sock = socket(AF_INET, SOCK_RAW, IPPROTO_RAW)) == INVALID_SOCKET)
throw Exception("socket setup error!");

//设置IP头操作选项
if (setsockopt(sock, IPPROTO_IP, IP_HDRINCL, (char*)&flag, sizeof(flag)) == SOCKET_ERROR)
throw Exception("setsockopt IP_HDRINCL error!");

//获取本机名
if (gethostname((char*)LocalName, sizeof(LocalName)-1) == SOCKET_ERROR)
throw Exception("gethostname error!");

//获取本地 IP 地址
if ((pHost = gethostbyname((char*)LocalName)) == NULL)
throw Exception("gethostbyname error!");

addr_in.sin_addr = *(in_addr *)pHost->h_addr_list[0]; //IP
addr_in.sin_family = AF_INET;
addr_in.sin_port = htons(57274);

//把 sock 绑定到本地地址上
if (bind(sock, (PSOCKADDR)&addr_in, sizeof(addr_in)) == SOCKET_ERROR)
throw Exception("bind error!");
出现无法绑定的现象，提示错误是协议家族没有装入系统，问为什么？该怎么办？

可能是你没有安装完全tcp协议
