ChronoEnd (Function)

In french: ChronoFin

Stops a stopwatch and returns the time elapsed (in milliseconds) since the start of timing (call to ChronoStart). This stopwatch can be restarted by ChronoResume if necessary.

Example

// Start the stopwatch
ChronoStart()
MyFunction()
// Stop the stopwatch
DurationMyFunction is Duration = ChronoEnd()
Info("The MyFunction() process lasted " + DurationMyFunction)

// Start the first stopwatch
ChronoStart(1)
// Start the second stopwatch
ChronoStart(2)
// Stop the first stopwatch
DurationChronoStart is Duration = ChronoEnd(1)
MyFunction()
// Stop the second stopwatch
DurationMyFunction is Duration = ChronoEnd(2)
Info("MyFunction() process lasted" + DurationMyFunction, ...
"The whole process lasted " + DurationChronoStart)

Versions 24 and later

MyChrono1 is Chrono
MyChrono2 is Chrono
// Start the first stopwatch
ChronoStart(MyChrono1)
// Start the second stopwatch
ChronoStart(MyChrono2)
// Stop the first stopwatch
DurationChronoStart is Duration = ChronoEnd(MyChrono1)
MyFunction()
// Stop the second stopwatch
DurationMyFunction is Duration = ChronoEnd(MyChrono2)
Info("The MyFunction() process lasted " + DurationMyFunction, ...
"The whole process lasted " + DurationChronoStart)

Syntax

Ending the timing started with a stopwatch number Hide the details

<Result> = ChronoEnd([<Stopwatch number>])

<Result>: Duration

Time elapsed (in milliseconds) since the last call to ChronoStart for the specified stopwatch number.
This parameter is an integer.

<Stopwatch number>: Optional integer

Identifier of stopwatch used. If this parameter is not specified, its default value is set to 1.

Versions 24 and later

Stopping the timing started with a Chrono variable Hide the details

<Result> = ChronoEnd(<Stopwatch>)

<Result>: Duration

Time elapsed (in milliseconds) since the last call to ChronoStart for the specified stopwatch.

<Stopwatch>: Chrono variable

Name of the Chrono variable that corresponds to the stopwatch to use.

New in version 24

Stopping the timing started with a Chrono variable Hide the details

<Result> = ChronoEnd(<Stopwatch>)

<Result>: Duration

Time elapsed (in milliseconds) since the last call to ChronoStart for the specified stopwatch.

<Stopwatch>: Chrono variable

Name of the Chrono variable that corresponds to the stopwatch to use.

Stopping the timing started with a Chrono variable Hide the details

<Result> = ChronoEnd(<Stopwatch>)

<Result>: Duration

Time elapsed (in milliseconds) since the last call to ChronoStart for the specified stopwatch.

<Stopwatch>: Chrono variable

Name of the Chrono variable that corresponds to the stopwatch to use.

Remarks

Miscellaneous

If ChronoEnd is called twice on the same stopwatch without ChronoStart being called, the returned duration will be identical for the two calls (the stopwatch is stopped during the first call to ChronoEnd).

Error

A WLanguage error occurs ("The stopwatch is not started") if ChronoStart was not called before ChronoEnd.

Threads and parallel tasks

Each thread (and each parallel task) includes its own stopwatches.

Two distinct threads (or two distinct parallel tasks) can perform separate timings by using the same stopwatch number.

The WLanguage error "The stopwatch is not started" will occur only if ChronoStart and ChronoEnd are not called in the same thread.
