Member Function Documentation

◆ End()

int64_t ns3::SystemWallClockMs::End ( void  )

Stop measuring the time since Start() was called.

Returns
the measured elapsed wall clock time (in milliseconds) since Start() was invoked.

It is possible to start a new measurement with Start() after this method returns.

Returns int64_t to avoid dependency on clock_t in ns-3 code.

◆ GetElapsedReal()

int64_t ns3::SystemWallClockMs::GetElapsedReal ( void  ) const
Returns
the measured elapsed wall clock time (in milliseconds) since Start() was invoked.

◆ GetElapsedSystem()

int64_t ns3::SystemWallClockMs::GetElapsedSystem ( void  ) const
Returns
the measured elapsed 'system' wall clock time (in milliseconds) since Start() was invoked.

Returns int64_t to avoid dependency on clock_t in ns-3 code.

◆ GetElapsedUser()

int64_t ns3::SystemWallClockMs::GetElapsedUser ( void  ) const
Returns
the measured elapsed 'user' wall clock time (in milliseconds) since Start() was invoked.

Returns int64_t to avoid dependency on clock_t in ns-3 code.
