Detailed Description

A trivial stop watch class for time measurement.

On Win32 the perfomance counter with a resolution of 0,313 microseconds is used, if available. If the performance counter is not available and on other systems the std::clock() function with a resolution of 0,055 milliseconds is used.

Example 1:

{ stopwatch s; dosomethingtimeconsuming(); }

The duration is written into cout.

Example 2: double d = 0.0;

{ stopwatch s(&d); dosomethingtimeconsuming(); }
