问题描述
我需要一个.Net的FileSystemWatcher模拟原始C ++ / WinAPI。
我几乎开始使用FindFirstChangeNotification / FindNextChangeNotification自己编码一个，但是我发现我可能不是第一个需要这个的人，也许有人愿意分享。
I need a .Net's FileSystemWatcher analog in raw C++/WinAPI.I almost started to code one myself using FindFirstChangeNotification/FindNextChangeNotification, but then it occurred to me that I am probably not the first one who needs this and maybe someone will be willing to share.
理想情况下，我需要的是一个类，可以使用如下：
Ideally what I need is a class which can be used as follows:
FileWatcher fw;
fw.startWatching("C:\MYDIR", "filename.dat",
FileWatcher::SIZE | FileWatcher::LAST_WRITE,
&myChangeHandler);
...
fw.stopWatching();
或者如果它会使用像boost :: signal这样会更好。
但是，除了标准库之外，没有依赖项，boost和raw WinAPI。
谢谢！
Or if it would use somehting like boost::signal it would be even better.But please, no dependencies other than the Standard Library, boost and raw WinAPI.Thanks!
推荐答案
ReadDirectoryChangesW函数呢？
What about the ReadDirectoryChangesW function?
它会将通知存储在缓冲区中，以便不会漏掉任何更改（除非缓冲区溢出）
It stores notifications in a buffer so you don't miss any changes (unless the buffer overflows)
这篇关于是否有人在C ++ / WinAPI中有类似FileSystemWatcher的类？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
