Detailed Description

Structure added to the end of each allocated block.

When a block is allocated from a HeapTrack heap with a size, internally HeapTrack calls Memory_alloc on the configured heap. The value of sizeof(HeapTrack_Tracker) is added to the requested size.

For example, if the caller makes the following call (where heapHandle is an HeapTrack handle that has been converted to an IHeap_Handle).

buf = Memory_alloc(heapHandle, MYSIZE, MYALIGN, &eb);

Internally, HeapTrack will make the following call (where size is MYSIZE, align is MYALIGN and obj is the HeapTrack handle).

block = Memory_alloc(obj->heap, size + sizeof(HeapTrack_Tracker), align, &eb);

When using HeapTrack, depending on the actual heap, you might need to make adjustments to the heap (e.g. increase the blockSize if using a HeapBuf instance).

The HeapTrack module manages the contents of this structure and should not be directly accessing them.
