One option is to license the disk formatting package from Apple Software
Licensing, at +1 408 974 9159.  Last I saw, it was $50 per product-year.
(Provided as EDASM assembly source code which you can adapt to your
needs and your assembler.)

If you *don't* need to support 5.25" disks, formatting any other sort
of device and laying down an empty directory is not too tough--you can
do it yourself based on information in the ProDOS 8 Technical Reference
Manual.

If you *do* need to support 5.25" disks and don't want to license code
from Apple, maybe somebody will explain HyperFormat...it's been a while,
but I think it's PD source code for formatting 5.25 disks.
