Detailed Description
Data Structure Documentation
◆ MEMBlockHeapTracking
| struct MEMBlockHeapTracking |
Definition at line 19 of file memblockheap.h.
| Data Fields | ||
|---|---|---|
| MEMBlockHeapBlock * | blocks | Pointer to first memory block. |
| uint32_t | blockCount | Number of blocks in this tracking heap. |
◆ MEMBlockHeapBlock
| struct MEMBlockHeapBlock |
Definition at line 33 of file memblockheap.h.
| Data Fields | ||
|---|---|---|
| void * | start | First address of the data region this block has allocated. |
| void * | end | End address of the data region this block has allocated. |
| BOOL | isFree | TRUE if the block is free, FALSE if allocated. |
| MEMBlockHeapBlock * | prev | Link to previous block, note that this is only set for allocated blocks. |
| MEMBlockHeapBlock * | next | Link to next block, always set. |
◆ MEMBlockHeap
| struct MEMBlockHeap |
Definition at line 57 of file memblockheap.h.
| Data Fields | ||
|---|---|---|
| MEMHeapHeader | header | |
| MEMBlockHeapTracking | defaultTrack | Default tracking heap, tracks only defaultBlock. |
| MEMBlockHeapBlock | defaultBlock | Default block, used so we don't have an empty block list. |
| MEMBlockHeapBlock * | firstBlock | First block in this heap. |
| MEMBlockHeapBlock * | lastBlock | Last block in this heap. |
| MEMBlockHeapBlock * | firstFreeBlock | First free block. |
| uint32_t | numFreeBlocks | Free block count. |
