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.

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

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.

Definition at line 187 of file unix-system-wall-clock-ms.cc.

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.

Definition at line 180 of file unix-system-wall-clock-ms.cc.

References ns3::SystemWallClockMsPrivate::GetElapsedUser(), m_priv, and NS_LOG_FUNCTION.

Start()

void ns3::SystemWallClockMs::Start

(

void

)

Start a measure.
