I've implemented a scrolling display of the contents of a removable storage
card directory, and it seems to work under an emulated OS 4.0 ROM. The code
uses a table and the VFSDirEntryEnumerate API call to do its job, but I'm
concerned that it's relying on behavior of that API call that it shouldn't.
I've noticed that the value of the dirEntryIteratorP argument is set to 1
after enumerating the first entry, and changes monotonically by 1
thereafter. Additionally, the API call tolerates using an arbitrary (but
valid) value on input to it for scrolling purposes, even if the containing
folder has been closed and reopened.
Since I know for certain that this does NOT work on a Sony Clie running OS
3.5 (it implements the same file system API), I'm wondering if this
technique is kosher or not. Anybody know?
Thanks,
Mark Peters
