Detailed Description

The 'classic' ICMP format ping. SOCK_RAW, IPPROTO_ICMP converts MSGTYPE_TYPE to ICMP_ECHO, ICMP_ECHOREPLY, ICMP_IREQ, ICMP_IREQREPLY ICMP_TSTAMP, ICMP_TSTAMPREPLY ?

Member Function Documentation

◆ CheckPingPacket()

HRESULT GrayLib::cPingICMP4::CheckPingPacket	(	const BYTE *	pData,
		size_t	iLen,
		size_t *	pnPayloadOffset
	)		const

overridevirtual

Assume we get raw IP4 data back.

Note: Payload may be padded out to 18 bytes if less.

Returns: MSGTYPE_TYPE

◆ MakePingPacket()

size_t GrayLib::cPingICMP4::MakePingPacket	(	OUT BYTE *	pData,
		MSGTYPE_TYPE	eMsgType,
		const void *	pPayload,
		size_t	nPayloadSize
	)		const

overridevirtual

Make ICMP packet for socket(AF_INET, SOCK_RAW, IPPROTO_ICMP)

Member Data Documentation

◆ k_SIZE_MAX

const size_t GrayLib::cPingICMP4::k_SIZE_MAX = 76

static

MAXICMPLEN = max size for ICMP ping.
