(Fyi: they are DosFindNotify...(), not just DosNotify...()).

I can't even find these in my 1.x header files.

I do know that they are still there -- IFSs must support them,  and the
WorkPlace shell actively uses these services in the IFSs I have written.

Try prototyping them yourself and using them.

[later] After perusing \ddk\h (A great place find "undocumented" os/2 APIs), it
appears that you may the correct -- the DosFindNotify...() apis no long exist
as
32bit apis (but you can still import the 16bit ones if if like).

They appear to have been replaced by something better (which probably uses the
FindNotify IFS services underneath).  You'll have to figure these out on your
own (please report back here);but they don't look too hard:
