ostream& Pinger::dbg

(

)

[inline]

get the ostream for user interaction

void Pinger::next_ping	(	gea::Handle *	h,
		gea::AbsTime	t,
		void *	data
	)			[static]

send the next ping packet

int Pinger::parse_opts	(	int	argc,
		const char *const *	argv
	)

parse the given options

Parameters:

	argc	number of arguments
	argv	vector of string pointers

Returns:

-1 on error, 0 otherwise.

void Pinger::ping_recv	(	BasePacket *	p,
		void *	data
	)			[static]

called when a ping packet is received

References awds::BasePacket::buffer, AbstractID< 6 >::fromArray(), out, awds::BasePacket::ref(), and awds::BasePacket::unref().

void Pinger::print_stats

(

std::ostream &

out

)

prints summary after stopping the ping session

Parameters:

out

ostream to write the text to.

References dest, numReceived, numTransmitted, and sumRTT.

void Pinger::resetStats

(

)

reset the internal state

reset the ping stats.

int Pinger::startPing

(

Handle *

h = 0

)

start ping

start the client side of the ping protocol

Parameters:

h

handle of interactive shell, used for generating periodic events and for stopping the ping

Returns:

-1 on error, 0 on success
