The sequence of callbacks reflects the PDB/PFC file structure. 72 Byte
header, series of 10 bytes for each record/resource info block, and the
the various records/resources.
The info blocks contain information about the size of the records(Offset
into the file stream for the start of the record. With offset of the
next record you can get size) , therefore if you tell the os that there
is less data than the header+Info blocks say, it is a corrupt database.
i.e. if the record is 2500 bytes, you will get asked for a 2 blocks of
1024 bytes, and a block of 452 bytes.
The only time you can return less bytes than the OS asks for is for the
last record. There is no information about its size, so the OS will
accept a smaller buffer.
