My idea was to have the whole if else in an inline function.
But I see that even the whole functionality can move to a helper.
Something like this:
static inline ULONGLONG get_qpctime(void)
{
LARGE_INTEGER stamp, freq;
QueryPerformanceCounter(&stamp);
QueryPerformanceFrequency(&freq);
if(freq.QuadPart == 10000000)
return stamp.QuadPart;
else
return stamp.QuadPart / freq.QuadPart * 10000000
+ stamp.QuadPart % freq.QuadPart * 10000000 /
freq.QuadPart;
}
bye
