Hello,

I'm currently trying to create a small Go tool that could deal with mdb
files.

I'm currently reading the HACKING file at
https://github.com/brianb/mdbtools/blob/master/HACKING to be able to decode
a Jet4 file for now.

I don't really understand the definition of tdef_pg in the data page
section.

Is it the index of the page within the whole file ? Is it an offset
relative to the beginning of the file ?

I fall on this page speaking about tdef_pg on sourceforge :
http://sourceforge.net/p/mdbtools/mailman/message/3267842/

I created a small program printing all the headers of the data pages and I
did not get the offset mentionned in this page.
Moreover, on this page, a page_id is mentioned but no trace in the HACKING
file.

Could someone give me more information about the tdef_pg pointer and more
generally,
how is a data definition page found from the data page header ?

Yannick
