- As far as I know, the 21 reserved bytes in the DTA aren't documented
- officially anywhere.
-
- Anyway, here's what I know about it:
-
- Byte Contents
-
- 0-11 search mask from Fsfirst() in the directory, i. e. w/o path
- 12 search attribute from Fsfirst()
- 13-16 offset in the search directory (byte position, thus always
- k*32) -- really silly to put a long to an odd address...
- 17-20 pointer to some kind of directory descriptor in GEMDOS'
- internal data
-
- So, bytes 13-16 are unique in one directory, bytes 17-20 point to something
- containing information which directory it is, bytes 17-20 are almost
- certainly NOT usable to trace back which directory is accessed, if you
- don't examine the structure they point to.
