Enumeration Type Documentation

StopWatchMode

enum StopWatchMode

strong

Mode at which the StopWatch should work.

Enumerator
MultiCPU	The StopWatch works safe in multi-CPU environments. For that, some degree of accuracy is lost, because under Windows the timers, that are safe to use on a multi-CPU system, are limited to 1 ms granularity.
SingleCPU	The StopWatch works with a granularity of less than 1 ms (basically with what the Windows SDK function QueryPerformanceFrequency returns). However, a time generated with this mode will not be safe to use in a multi-CPU (not multi-core!) environment because, a thread may travel between CPUs and the timers are not synchronized between CPUs.
