The PDB (Pilot Database) file format is used by all models of the Palm Pilot and
IBM Workpad. The format consists of a header followed by a set of record
headers followed by the records themselves.
In the SYNOPSIS above, the types ``Byte,'' ``Word,'' and ``DWord'' are used just
as in the Pilot headers. The type ``Byte'' is 8 bits; ``Word'' is 16 bits;
``DWord'' is 32 bits. The latter two are in big-endian format.
- 1.
- The C structures given in the SYNOPSIS above are
illustrative and most likely will not work in actual C code since
compilers align data members on word boundaries.
- 2.
- The PDB file format presented here is not official and was
written at the time when PDB file format was not public. It is possibly
outdated. The official standard is available on the Palm web page. (SEE
