IN HANDLE DirectoryObjectHandle, OUT POBJDIR_INFORMATION DirObjInformation, IN ULONG BufferLength, IN BOOLEAN GetNextIndex, IN BOOLEAN IgnoreInputIndex, IN OUT PULONG ObjectIndex, OUT PULONG DataWritten OPTIONAL );




DirectoryObjectHandle
Handle to Directory Object opened with DIRECTORY_QUERY access.
DirObjInformation
Pointer to OBJDIR_INFORMATION structure. Warning: structure has variable length dependly to length of object name. To test for required length of buffer use DataWritten parameter.
BufferLength
