typedef _W64 unsigned int UINT_PTR, *PUINT_PTR;
typedef UINT_PTR SOCKET;
#define INVALID_SOCKET (SOCKET)(~0)
(~0)的值为-1；
(SOCKET)(~0)的值为：十六进制0xFFFFFFFF（十进制4294967295）。
To abort a connection, release a socket handle, and discard data pending for writing, do:
closesocket(sock);
sock = INVALID_SOCKET; // do not make further use of sock.
To flush a sock handle, gracefully close the socket, and release the socket handle in the
background:
DisconnectEx(sock, NULL, 0, 0); // retrieve this function pointer with WSAIoctl(WSAID_DISCONNECTEX).
closesocket(sock);
sock = INVALID_SOCKET; // do not make further use of sock.
