LLGL::Timer Namespace Reference

Functions
LLGL_EXPORT std::uint64_t	Frequency ()
	Returns the timer frequency of the OS. This is the number of ticks per seconds, e.g. 1,000,000 for microseconds.
LLGL_EXPORT std::uint64_t	Tick ()
	Returns the current 'tick' of a high resolution timer that is OS dependent. The tick frequency can be queried with Frequency.

Frequency()

LLGL_EXPORT std::uint64_t LLGL::Timer::Frequency

(

)

Returns the timer frequency of the OS. This is the number of ticks per seconds, e.g. 1,000,000 for microseconds.

Tick()

LLGL_EXPORT std::uint64_t LLGL::Timer::Tick

(

)

Returns the current 'tick' of a high resolution timer that is OS dependent. The tick frequency can be queried with Frequency.

Remarks

The following example illustrates how to query the elapsed time in milliseconds between two time stamps:

const std::uint64_t startTime = LLGL::Timer::Tick();
// Some events ...
const std::uint64_t endTime = LLGL::Timer::Tick();
const double elapsedSeconds = static_cast<double>(endTime - startTime) / LLGL::Timer::Frequency();
printf("Elapsed time: %f ms\n", elapsedSeconds * 1000.0);
