Detailed Description

A RawPacket specialization used by WinDivertDevice.

In addition to the base RawPacket data (raw buffer, timestamp and link-layer type), WinDivert also provides the Windows network interface index and the original WinDivert timestamp. These can be retrieved with getInterfaceIndex() and getWinDivertTimestamp() respectively.

Member Function Documentation

◆ getInterfaceIndex()

uint32_t pcpp::WinDivertRawPacket::getInterfaceIndex ( ) const
inline

Get the Windows interface index the packet was captured on.

Returns
The interface index as reported by WinDivert.

◆ getWinDivertTimestamp()

uint64_t pcpp::WinDivertRawPacket::getWinDivertTimestamp ( ) const
inline

Get the original WinDivert timestamp captured for this packet.

Returns
A 64-bit timestamp value as returned by WinDivert (see WinDivert docs for units and origin).
