FileIo_DirEnum class
This class is the event type class for the enumerate directory and directory notification events.
The following syntax is simplified from MOF code.
[EventType{72, 77}, EventTypeName{"DirEnum", "DirNotify"}]
class FileIo_DirEnum : FileIo
{
uint32 IrpPtr;
uint32 TTID;
uint32 FileObject;
uint32 FileKey;
uint32 Length;
uint32 InfoClass;
uint32 FileIndex;
string FileName;
};
The FileIo_DirEnum class has these types of members:
The FileIo_DirEnum class has these properties.
-
FileIndex
-
-
