Anyone know where i could find docs/details on these:
cluster_read()
cluster_write()
They're currently not documented. The only details are in the source.
(I'm trying to intercept the lowest-level calls from the hfs+ source
to the underlying partition- are these the right functions to be
looking at? this is for my own purposes with a custom-built hfs+
kext, not for shipping code...)
Hmmm, are you looking for the pattern of block reads/writes? If so,
you may be better off working at the IOMedia level. This is
discussed in the "Developing a Filter Scheme" section of "Inside Mac
OS X: Writing Drivers for Mass Storage Devices".
