windows socket ipv6 SOCK_RAW

bind处一直报错WSAEADDRNOTAVAIL10049，不知道为什么？

WSAEADDRNOTAVAIL 10049

Cannot assign requested address. The requested address is not valid in its context. This normally results from an attempt to bind to an address that is not valid for the local computer. This can also result from connect, sendto, WSAConnect, WSAJoinLeaf, or WSASendTo when the remote address or port is not valid for a remote computer (for example, address or port 0).
