       SOCKET s,
       WSABUF *  lpBuffers,
       DWORD dwBufferCount,
       DWORD *  lpNumberOfBytesRecvd,
       DWORD *  lpFlags,
       sockaddr *  lpFrom,

   )

Receive a datagram and store the source address using overlapped I/O.

Parameters

`s`	Socket descriptor.
`lpBuffers`	Array of WSABUF structures.
`dwBufferCount`	Number of WSABUF structures.
`lpNumberOfBytesRecvd`	Receives bytes transferred (if completed immediately).
`lpFlags`	Flags (modified on return).
`lpFrom`	Receives the source address.
`lpFromlen`	On input, size of lpFrom buffer; on output, actual size.
`lpOverlapped`	Overlapped structure for async operation.
`lpCompletionRoutine`	Completion routine (usually null for IOCP).

Returns

0 on immediate success, SOCKET_ERROR on error or pending.
