Function Documentation

DtlsClient_connect()

void* DtlsClient_connect	(	void *	obj,
		struct rte_mbuf **	inPkts,
		unsigned int	inCount,
		unsigned int *	sendCount,
		unsigned int *	freeCount,
		uint32_t	srcIP,
		uint16_t	srcPort
	)

Add one connection to the State Machine.

Parameters

obj	The void* returned from DtlsClient_init()
inPkts	mbufs from MoonGen
inCount	Number of buffers in inPkts (should be 1)
sendCount	This will be set to the number of packets to be sent
freeCount	This will be set to the number of packets to be freed
srcIP	IP which should be used as the source
srcPort	Port which should be used as the source

Returns

Opaque object to be fed into DtlsClient_getPkts
