一段D7可以编译通过的代码在delphi 10.2.3上编译不通过，求...
部分代码：procedure TFileWatchThread.Execute;
var
numBytes: DWORD;
CompletionKey: DWORD;
begin
while not Terminated do
begin
GetQueuedCompletionStatus( FPCompletionPort^, numBytes, CompletionKey, FPOverlapped, INFINITE);
if CompletionKey <> 0 then
begin
Synchronize(HandleEvent);
FBytesWritten := 0;
ZeroMemory(@FNotificationBuffer, SizeOf(FNotificationBuffer));
ReadDirectoryChanges(FPDirectoryHandle^, @FNotificationBuffer,
SizeOf(FNotificationBuffer), WatchSubTree, FNotifyFilter,
@FBytesWritten, @FOverlapped, nil);
end
else
Terminate;
end;
end;
完整代码见附件，代码部分有点儿长，就没有全部贴出来。

出错提示： Unit1.pas(185): E2033 Types of actual and formal var parameters must be identical
用D7可直接编译没有问题，换成delphi 10.2.3编译就不行了。求大神带路。~
出错点就在 GetQueuedCompletionStatus( FPCompletionPort^, numBytes, CompletionKey, FPOverlapped, INFINITE); 这一句。。
找到原因了，delphi 10.2.3 修改了这个函数定义：
function GetQueuedCompletionStatus(CompletionPort: THandle;
var lpNumberOfBytesTransferred: DWORD; var lpCompletionKey: ULONG_PTR;
var lpOverlapped: POverlapped; dwMilliseconds: DWORD): BOOL; stdcall;
所以出错的位置这样子修改：
GetQueuedCompletionStatus( FPCompletionPort^, numBytes, ULONG_PTR(CompletionKey), FPOverlapped, INFINITE);
就可以编译通过了。。
谢谢提示，记下了
