Inside Macintosh: Memory
This section describes the organization of heap zones and block headers. In general, you do not need to know how the Memory Manager organizes heap zones or block headers if your application simply allocates and releases blocks of memory. The information described in this section is used by the Memory Manager for its own purposes. Developers of some specialized applications and utilities might, however, need to know exactly how zones and block headers are organized. This information is also sometimes useful for debugging.
This section is provided primarily for informational purposes. The organization and size of heap zones and block headers is subject to change in future system software versions.<36pt>
