В коде функция
ReadDirectoryChangesW() возвращает ноль:
C++ (Qt)
#define pathDir "Z:\\"
DWORD WINAPI ThreadFunc(LPVOID lpParam)
{
HANDLE hDir = CreateFile(_T(pathDir), // pointer to the file name
FILE_LIST_DIRECTORY, // access (read/write) mode
FILE_SHARE_READ|FILE_SHARE_WRITE|FILE_SHARE_DELETE, // share mode
NULL, // security descriptor
OPEN_EXISTING, // how to create
FILE_FLAG_BACKUP_SEMANTICS, // file attributes (FILE_FLAG_OVERLAPPED)
NULL); // file with attributes to copy
const DWORD dwNotificationFlags = FILE_NOTIFY_CHANGE_LAST_WRITE | FILE_NOTIFY_CHANGE_FILE_NAME;
FILE_NOTIFY_INFORMATION Buffer[1024];
DWORD BytesReturned;
VOID *pBuf = (BYTE*)&Buffer;
while (ReadDirectoryChangesW(hDir, // handle to directory
&Buffer, // read results buffer
sizeof(Buffer), // length of buffer
TRUE, // monitoring option
dwNotificationFlags,
&BytesReturned, // bytes returned
NULL, // overlapped buffer
NULL)) // completion routine
{
FILE_NOTIFY_INFORMATION* pInfo = (FILE_NOTIFY_INFORMATION*) pBuf;
SelectAction(pInfo);
}
dwError = GetLastError();
CloseHandle(hDir);
return 0;
}
GetLastError() выдает, что код ошибки
ERROR_INVALID_FUNCTION Incorrect function.На
MSDN ReadDirectoryChangesW Function есть такое:
Return Value

Нужен алгоритм пишут:
"Я проверял только на сетевом диске с NTFS. Там ReadDirectoryChangesW работал."
