access heap statistic for c-heap (malloc/free)

[boaks]

I would like to include some memory heap statistic into a remote health message.
I found int sys_heap_runtime_stats_get(struct sys_heap *heap, struct sys_heap_runtime_stats *stats);
That requires to pass in a struct sys_heap *heap. So, is it possible to access the heap which is used for the c-functions malloc/free?
