Macro Definition Documentation

◆ DELAY

#define DELAY ( time )

Value:

(((time) < (Simulator::Now ())) ? Seconds (0.000001) : \

(time - Simulator::Now () + Seconds (0.000001)))

ns3::Seconds

Time Seconds(double value)

Construct a Time in the indicated unit.

Definition: nstime.h:1014

ns3::Now

Time Now(void)

create an ns3::Time instance which contains the current simulation time.

Definition: simulator.cc:365

Gets the delay between a given time and the current time.

If given time is previous to the current one, then this macro returns a number close to 0. This is used for scheduling events at a certain moment.
