Creates a BStopWatch object, names it, and starts its timer. If silent is false (the default), the object will print its elapsed time when it's destroyed; otherwise the message isn't printed. To get the elapsed time from a silent BStopWatch, call ElapsedTime().

Stops the object's timer, prints a timing message to standard out (unless it's running silently), and then destroys the object. By default the timing message looks like this:

StopWatch "name": f usecs.

If you've recorded some lap points (through the Lap() function), you'll also see the lap times as well:

StopWatch "name": f usecs.
[lap#: soFar#thisLap] [lap#: soFar#thisLap] [lap#: soFar#thisLap]...

…where lap# is the number of the lap, soFar was the total elapsed time at that lap, and thisLap was the time it took to complete the lap.

Returns the elapsed time, in microseconds, since the object was created or last Reset(). This function doesn't print the time message, nor does it touch the timer (the timer keeps running—unless it's Suspend()ed).

BStopWatch watch("Timer 0");
...
printf("Elapsed time: %Ldn", watch.ElapsedTime());

Records a "lap point" and returns the total elapsed time so far. The lap point times are printed individually when the object is destroyed, provided the object isn't silent. You can record as many as eight lap points; if you ask for a ninth lap point, the lap isn't recorded and this function returns 0. See ~BStopWatch() for a description of what the lap points look like when they're printed.

Returns the name of the object, as set in the constructor.

These functions affect the object's timer.

Suspend() stops the timer but doesn't reset it.

Resume() starts the timer running again.

Reset() sets the elapsed time to 0, but doesn't stop the timer. You can call Reset() at any time, regardless of whether the object is running or suspended.
