Question

it works when iam trying to bind to my auto-config link local address. but when i try to bind to some manually assigned IPv6 address bind() fails with 10049 error. here is the code

bool StartServer()
{
  const char *Ip = " fe80::216:76ff:fe12:2661%4";
  SHORT nIPFamily = -1;
  int dSock;
  union 
 {
   struct sockaddr_in  saddr4;
   struct sockaddr_in6  saddr6;
 }ServerIP;

午餐会(和;ServerIP,0,sizeof(ServerIP);

 if(strstr(Ip,":"))
 {
   UCHAR MyIp[16];
   USHORT ScopeId = 0;
   ServerIP.saddr6.sin6_family = nIPFamily = AF_INET6;
   ServerIP.saddr6.sin6_port = htons( nPort );
   StringToAddress( Ip, MyIp ); //common function to convert string to address (16byte)
   memcpy( ServerIP.saddr6.sin6_addr.u.Byte, MyIp,16 );
   sscanf(strstr(Ip,"%")+1,"%d",&ScopeId);
   ServerIP.saddr6.sin6_scope_id = ScopeId;
   nAddLen = sizeof(sockaddr_in6);
   psockaddr = &ServerIP.saddr6;
 }

 if ((dSock = socket(nIPFamily, SOCK_STREAM, 0)) < 0)
 {
   AfxMessageBox("Failed to create server socket");
   return -1;
 }
 if (bind (dSock, (sockaddr*)psockaddr, nAddLen) < 0)
 {
   char errmsg[128];
   sprintf(errmsg,"Bind Failed with error %d",WSAGetlastError());
   AfxMessageBox(errmsg);
   return -1;
 }

请提出咨询意见。超过2天,我 st!

问题:你是否正在使用Pipv6-aware PC(例如,Vista或Win7)?

Answer 2

只有在使用全球预测时,才有链接-当地地址的使用范围,而不是增加。
