[Yaffs] yaffs/direct: no '.' or '..' ?

Hello list,

I am making progress with implementing YAFFS on eCos (on top of my
work-in-progress NAND flash controller). I can make files, directories,
list dirs, remove files and directories, etc. One of the obstacles was
that I had to find out that _block_query() must read the spare area to
see if there is a chunkUsed value. One for the documentation?

Now I meet a problem:

when I yaffs_opendir()/yaffs_readdir() a directory, I see no mention of
the directories '.' and '..' .
Is that correct?
If yes, is that intentional?
If yes, I guess my wrapper layer must provide them; if I perform
opendir()/readdir() under Linux, I see '.' and '..' listed.

On the other hand, I can see consistency:
= if I do yaffs_stat("."), I get an ENOENT error;
= if I chdir into some directory and chdir(".."), I get an ENOENT error.

Should my library wrapper resolve '.' and '..' before entering
yaffs_direct calls?

Thanks for advice,
