Use a standard i/o request (via DoIO()). Use 'key' number times
block size as the io_Offset value in the IOStdReq structure.
Look in Chapter 19 of the ROM Kernel Manual…Libraries and
Devices.
As to pointers and so forth…that you'll have to deal with in your
own code by interpreting the data in the block…or by searching for the
parent block (depending on if FFS or OFS).
