Wrong iterator value returned from `dlp_VFSDirEntryEnumerate`
The description of dlp_VFSDirEntryEnumerate says:
- Supported on Palm OS 4.0 and later. At the beginning you set
- @p dirIterator to #vfsIteratorStart, then call this function
- repeatedly until it returns an error code or the iterator becomes
- #vfsIteratorStop
This does not work. After the first invocation diriterator becomes always vfsIteratorStop, even if there are more than diritems files in the directory. In rare cases, diriterator even becomes 1888 when enumerating few items from the SDCard volume.
Please see my small plugin code in the attachment !
From the while loop in function backupMedia() I get only 4 of 9 file entries:
Opened root '/Photos & Videos' on volume 1
Enumerate root '/Photos & Videos', dirRef=682033264, itr=0, dirItems=4
Enumerate OK: bytes=196, dirRef=682033264, itr=-1, dirItems=4
Now search for albums to fetch ...
Found album candidate 'AllAlbum.db'
Found album candidate 'CollectData.db'
Found album candidate 'Foto_120820_001.jpg'
Found album candidate '#Thumbnail'
From the for loop as a workaround in function fetchAlbum() all 9 files are found:
Fetching album 'Unfiled' in '/Photos & Videos' on volume 1 ...
Enumerate album '/Photos & Videos', dirRef=681640048, itr=0, dirItems=4
Enumerate OK: bytes=196, dirRef=681640048, itr=-1, dirItems=4
Enumerate album '/Photos & Videos', dirRef=681640048, itr=0, dirItems=8
Enumerate OK: bytes=196, dirRef=681640048, itr=-1, dirItems=8
Enumerate album '/Photos & Videos', dirRef=681640048, itr=0, dirItems=16
Enumerate OK: bytes=196, dirRef=681640048, itr=-1, dirItems=9

From enummeration on SDCard volume I even get 1888 for itr:

Is there anyway you can commit a PR for this? I don't have a working Palm to test this with.

I plan to develop some patches to fix this and other bugs in libpisock / pilot-link, and then to clean-up my workarounds in JPilotMediaPlugin ... some day ;-)
