FUNCTIONS:

QueryPerformanceCounter

Retrieves the current value of the performance counter, which is a high resolution (<1us) time stamp that can be used for time-interval measurements.

Syntax:
BOOL QueryPerformanceCounter(
[out] LARGE_INTEGER *lpPerformanceCount
);
Parameters:
[out] lpPerformanceCount

A pointer to a variable that receives the current performance-counter value, in counts.

Return value
If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError. On systems that run Windows XP or later, the function will always succeed and will thus never return zero.

Examples
// Gets the current number of ticks from QueryPerformanceCounter. Throws an
// exception if the call to QueryPerformanceCounter fails.
static inline int64_t GetTicks()
{
LARGE_INTEGER ticks;
if (!QueryPerformanceCounter(&ticks))
{
winrt::throw_last_error();
}
return ticks.QuadPart;
}

QueryPerformanceFrequency

Retrieves the frequency of the performance counter.
