#include <nitro/os.h>u32 OS_GetMaxFreeSize( OSArenaId id, OSHeapHandle heap );
| id | Arena ID of the arena for the heap from which the largest block is obtained |
| heap | Heap handle of the heap from which the largest block is obtained |
The size (in bytes) of the largest free block in the heap.
Obtains the size of the largest free block in heaps.
Set OS_CURRENT_HEAP_HANDLE in heap to specify the current heap.
The free block's header is not included in the size value. The size refers to the free block's data region.
All free blocks are tracked down and calculated, so the time required for the process is proportional to the amount of memory blocks.
