WinDivertRecvEX goes into blocking state when no packets #328

It is the sample from the example passthru.c.

When there is no packet in the interface, then this call goes in blocking state. Is anything else needs to be tuned ? if (!WinDivertRecvEx(handle, packet, packet_len, &recv_len, 0, addr, &addr_len, NULL))

For non-blocking, you need to pass a valid OVERLAPPED structure into WinDivertRecvEx. For more information, see the microsoft documentation for overlapped I/O.
