Apparently it is an XP-introduced Windows API function.

推荐答案

不可能直接调用该函数。但是您可以进行引用：

It's not possible to call the function directly. But you can make a reference:

// reference to the Windows function:
function GetProcessHandleFromHwnd(hwnd: HWND): THandle; external 'oleacc.dll' name 'GetProcessHandleFromHwnd'; stdcall;

// and you can call it from your own function:
function TryGetProcessHandle(const WindowHandle: THandle; var ProcessHandle: THandle): Boolean;
begin
  ProcessHandle := GetProcessHandleFromHwnd(WindowHandle);
  Result := (ProcessHandle <> 0);
end;
