ReadDirectoryChangesW 实现

发布于 2024-07-26 14:34:48 字数 269 浏览 7 评论 0原文

最初，我链接到此调用，以便我可以记录对某个文件的所有访问并捕获对其的所有更改。

我已经完成了几个例子，但都失败了。即使 msdn 代码也无法为我编译。

有人可以为我提供一个小的工作片段来监视文件并记录更改吗？

或者至少有一些指示？

谢谢

您可能没有声明 ReadDirectoryChangesW 的标头，或者需要 #define _WIN32_WINNT 大于或等于 0x0400。如果是前者，您可以手动获取 ReadDirectoryChangesW 的地址并调用：

HANDLE kernel32_dll_handle= LoadLibrary("kernel32.dll");
FARPROC ReadDirectoryChangesWAddress= GetProcAddress(kernel32_dll_handle, "ReadDirectoryChangesW");

typedef BOOL WINAPI (*ReadDirectoryChangesWDeclaration)(
  __in         HANDLE hDirectory,
  __out        LPVOID lpBuffer,
  __in         DWORD nBufferLength,
  __in         BOOL bWatchSubtree,
  __in         DWORD dwNotifyFilter,
  __out_opt    LPDWORD lpBytesReturned,
  __inout_opt  LPOVERLAPPED lpOverlapped,
  __in_opt     LPOVERLAPPED_COMPLETION_ROUTINE lpCompletionRoutine
);

ReadDirectoryChangesWDeclaration ReadDirectoryChangesW= (ReadDirectoryChangesWDeclaration)ReadDirectoryChangesWAddress;

You might not have the header that declares ReadDirectoryChangesW, or you need to #define _WIN32_WINNT as greater than or equal to 0x0400. If it's the former, you can manually get the address to ReadDirectoryChangesW and call that:

HANDLE kernel32_dll_handle= LoadLibrary("kernel32.dll");
FARPROC ReadDirectoryChangesWAddress= GetProcAddress(kernel32_dll_handle, "ReadDirectoryChangesW");

typedef BOOL WINAPI (*ReadDirectoryChangesWDeclaration)(
  __in         HANDLE hDirectory,
  __out        LPVOID lpBuffer,
  __in         DWORD nBufferLength,
  __in         BOOL bWatchSubtree,
  __in         DWORD dwNotifyFilter,
  __out_opt    LPDWORD lpBytesReturned,
  __inout_opt  LPOVERLAPPED lpOverlapped,
  __in_opt     LPOVERLAPPED_COMPLETION_ROUTINE lpCompletionRoutine
);

ReadDirectoryChangesWDeclaration ReadDirectoryChangesW= (ReadDirectoryChangesWDeclaration)ReadDirectoryChangesWAddress;
