为什么找不到 SIO_RCVALL 连MSDN都没有这个东西

为什么找不到 SIO_RCVALL 连MSDN都没有这个东西

在一个头文件里面有,但是具体名字我忘了不过用下面这句也可以解决
#define SIO_RCVALL _WSAIOW(IOC_VENDOR,1)

WSAIoctl
The WSAIoctl function controls the mode of a socket.

int WSAIoctl(
  SOCKET s,
  DWORD dwIoControlCode,
  LPVOID lpvInBuffer,
  DWORD cbInBuffer,
  LPVOID lpvOutBuffer,
  DWORD cbOutBuffer,
  LPDWORD lpcbBytesReturned,
  LPWSAOVERLAPPED lpOverlapped,
  LPWSAOVERLAPPED_COMPLETION_ROUTINE lpCompletionRoutine
);
Parameters
s
[in] Descriptor identifying a socket.
dwIoControlCode
[in] Control code of operation to perform.
lpvInBuffer
[in] Pointer to the input buffer.
cbInBuffer
[in] Size of the input buffer.
lpvOutBuffer
[out] Pointer to the output buffer.
cbOutBuffer
[in] Size of the output buffer.
lpcbBytesReturned
[out] Pointer to actual number of bytes of output.
lpOverlapped
[in] Pointer to a WSAOVERLAPPED structure (ignored for nonoverlapped sockets).
lpCompletionRoutine
[in] Pointer to the completion routine called when the operation has been completed (ignored for nonoverlapped sockets).

SIO_RCVALL
Enables a socket to receive all IP packets on the network. The socket handle passed to the WSAIoctl function must be of AF_INET address family, SOCK_RAW socket type, and IPPROTO_IP protocol. The socket also must be bound to an explicit local interface, which means that you cannot bind to INADDR_ANY.
Once the socket is bound and the ioctl set, calls to the WSARecv or recv functions return IP datagrams passing through the given interface. Note that you must supply a sufficiently large buffer. Setting this ioctl requires Administrator privilege on the local machine. SIO_RCVALL is available in Windows 2000 and later versions of Windows.
