TS_INLINE UDPPacket* new_UDPPacket

(

)

Create a new packet to be sent over UDPConnection.

Packet has no destination or data.

Definition at line 250 of file P_UDPPacket.h.

References udpPacketAllocator.

TS_INLINE UDPPacket* new_UDPPacket	(	struct sockaddr const *	to,
		ink_hrtime	when = 0,
		IOBufferBlock *	block = NULL,
		int	len = 0
	)

Create a new packet to be sent over UDPConnection.

This clones and makes a reference to an existing IOBufferBlock chain.

Parameters:

	to	address of where to send packet
	when	ink_hrtime relative to ink_get_hrtime_internal()
	block	if !NULL, then the IOBufferBlock chain of data to use for packet
	len	# of bytes to reference from block

TS_INLINE UDPPacket* new_UDPPacket	(	struct sockaddr const *	to,
		ink_hrtime	when = 0,
		char *	buf = NULL,
		int	len = 0
	)

Create a new packet to be sent over UDPConnection.

This actually copies data from a buffer.

Parameters:

	to	address of where to send packet
	when	ink_hrtime relative to ink_get_hrtime_internal()
	buf	if !NULL, then len bytes copied from buf and made into packet.
	len	# of bytes to copy from buf
