What are you trying to implement? Suspend to disk? Checkpointing?
Anyway, you will need to get inside the malloc implementation and add
extra functionality.
packages/services/memalloc/common/current
The default malloc implementation is to use dlmalloc. It is also
possible to use a variable size pool, ie cyg_mempool_var_*. You might
find this easier to understand and extend with what you need.
