Detailed Description

Factory and system-query abstraction used by WinDivertDevice.

The sole responsibilities of this interface are:

Creating IWinDivertHandle instances (which expose the WinDivert API surface).
Enumerating relevant Windows network interfaces. Keeping these responsibilities here keeps WinDivertDevice decoupled from concrete system/driver calls and enables unit testing and alternative implementations.

Member Function Documentation

virtual std::vector<NetworkInterface> pcpp::internal::IWinDivertDriver::getNetworkInterfaces ( ) const

pure virtual

Enumerate Windows network interfaces relevant to WinDivert.

Returns: A vector of NetworkInterface objects with index, name, description and status.

virtual std::unique_ptr<IWinDivertHandle> pcpp::internal::IWinDivertDriver::open	(	const std::string &	filter,
		int	layer,
		int16_t	priority,
		uint64_t	flags
	)

pure virtual

Open a WinDivert handle with the given filter and settings.

Parameters

[in]	filter	WinDivert filter string (see WinDivert documentation).
[in]	layer	WinDivert layer value (typically WINDIVERT_LAYER_NETWORK).
[in]	priority	Injection/capture priority (lower is higher priority).
[in]	flags	WinDivert open flags (sniff mode, fragments, etc.).

Returns: A unique_ptr to an IWinDivertHandle on success, or nullptr on failure.
