Problem in using VFSFileDBInfo on hidden storage heap volume on T5 and Treo 650

[Mark John Buenconsejo]

Hi, I'm developing an application that accesses a large PDB. The PDB file 
can be as big as 12MB. Now, I read that the DBCache on a T5/TREO 650 is 
only 10MB, so instead of accessing it normally using the Database manager, 
I will access it directly in the storage heap volume located in the flash 
memory.

Now, I noticed that the database are stored under a PALM_DM directory in 
the volume, and have filenames based on the Database name. Further, I 
noticed that the names are kind of encoded and does not have a .PDB extension.

I developed a code to enumerate all the files in the PALM_DM directory and 
identify the filename of the PDB I wanted to open. After it has located the 
file, it will try to open the file and determine the database type and 
creator. Now, VFSFileOpen works on the file, but when I do a VFSFileDBInfo 
(of course after the VFSFileOpen), it returns an error, vfsErrBadData.

I read from the documentation that I can use the VFS Manager functions to 
the files in the storage heap volume. I don't know what could be wrong -- 
if the volume is just like any other VFS compatible volume.

I speculate that VFSFileDbInfo expects a big-endian database, while the 
database files in the storage heap volume are stored as little-endian 
(native-ARM routines), making VFSFileDbInfo fail. What do you think?

Anyway, I hope someone can help me with this.
Thanks!
Mark
