Figure 5-2. Memory Allocation Trace Window
The program in Example 5-7 and Example 5-8 gives board-dependent
results. O indicates the original amount of memory, U the amount of memory
used, and A the length in MADUs of the largest contiguous free block of
memory. The addresses you see are likely to differ from those shown in
Example 5-2.
