- I don't know if this is your problem, but there is
- a bug in the documentation: to have DosDevIOCtl prototyped,
- you need INCL_DOSDEVICES and not INCL_DOSPROCESS.
- I strongly recommend that you always compile with /Kb to
- find all non-prototyped functions...
- IO CTLs are documented in "Physical Device Driver Reference".
