Function Documentation

◆ DetectPcrePayloadMatch()

int DetectPcrePayloadMatch	(	DetectEngineThreadCtx *	det_ctx,
		const Signature *	s,
		const SigMatchData *	smd,
		Packet *	p,
		Flow *	f,
		const uint8_t *	payload,
		uint32_t	payload_len
	)

Match a regex on a single payload.

Parameters

det_ctx	Thread detection ctx.
s	Signature.
sm	Sig match to match against.
p	Packet to set PktVars if any.
f	Flow to set FlowVars if any.
payload	Payload to inspect.
payload_len	Length of the payload.

Return values

1	Match.
0	No match.
