DECLARE_DELEGATE_ThreeParams() [1/2]

DECLARE_DELEGATE_ThreeParams	(	FOnLowLevelSend	,
		void *	,
		int32	,
		bool &
	)

Delegate for hooking the net connections 'LowLevelSend' (at the socket level, after PacketHandler parsing)

Parameters

Data	The data being sent
Count	The number of bytes being sent
bBlockSend	Whether or not to block the send (defaults to false)

DECLARE_DELEGATE_ThreeParams() [2/2]

DECLARE_DELEGATE_ThreeParams	(	FOnReceivedRawPacket	,
		void *	,
		int32	,
		bool &
	)

Delegate for hooking the net connections 'ReceivedRawPacket'

Parameters

Data	The data received
Count	The number of bytes received
bBlockReceive	Whether or not to block further processing of the packet (defaults to false)
