unsigned int cache

Definition at line 82 of file astmm.c.

Referenced by __ast_alloc_region(), handle_memory_show_allocations(), handle_memory_show_summary(), mm_atexit_regions_list(), and mm_atexit_regions_summary().

unsigned char data[0]

Location of the requested malloc block to return.

Note:

Must have the same alignment that malloc returns. i.e., It is suitably aligned for any kind of varible.

Definition at line 105 of file astmm.c.

Referenced by __ast_alloc_region(), mm_atexit_cmp(), mm_atexit_hash_restore(), mm_atexit_regions_list(), region_check_fences(), region_data_check(), region_data_wipe(), region_find(), and region_remove().

unsigned int fence

Lower guard fence.

Note:

Must be right before data[].

Padding between fence and data[] is irrelevent because data[] is used to fill in the lower fence check value and not the fence member. The fence member is to ensure that there is space reserved for the fence check value.
