- Kernel and I/O Kit APIs
All supported BSD kernel interfaces (KPIs) and system calls should already be 64-bit clean in Mac OS X v10.4.
The I/O Kit is being extended somewhat to include support for 64-bit applications.
These changes are primarily in the form of additional methods in the IOMemoryDescriptor class.
