In the world of Windows system programming, time is more than just a number—it's a critical measure for performance profiling, high-frequency trading, database logging, and real-time data acquisition. For years, Windows developers relied on GetSystemTimeAsFileTime to obtain the current system time. However, this function, while accurate to the millisecond, often fell short for sub-millisecond requirements.
Here's a useful article on the topic:
Use a Fallback: Implement a check to use GetSystemTimeAsFileTime (the standard version) if the OS is older than Windows 8. getsystemtimepreciseasfiletime windows 7 upd
The function GetSystemTimePreciseAsFileTime is not available on Windows 7; it was first introduced in Windows 8. If you are seeing an "Entry Point Not Found" error, it is because the software you are running was compiled to require this newer API. Here's a useful article on the topic: Use
typedef void (WINAPI *pGetSystemTimePreciseAsFileTime)(LPFILETIME lpSystemTimeAsFileTime);
static void InitFunction(void)
HMODULE hK32 = GetModuleHandleA("kernel32.dll");
if (hK32)
pGetSystemTimePreciseAsFileTime = (GetSystemTimePreciseAsFileTime_t)GetProcAddress(hK32, "GetSystemTimePreciseAsFileTime"); and real-time data acquisition. For years
