Hi there,

I'm trying to find some documentation on the extra arguments to free and realloc in the
ck_malloc struct.

Any pointers would be much appreciated.

Cheers, Ian.

Hi Ian,

The extra arguments to the free callback are number of bytes of region being deallocated and bool indicating whether the memory being destroyed is vulnerable to read-reclaim races (and so, extra precautions must be taken).

For realloc, the first size_t is current number of bytes of allocation and the second is the new number of bytes. The bool indicates the same thing as free, whether safe memory reclamation of some form might be needed.
