一、堆内存结构体

struct dummy_heap_mem
{
    void *(*k_alloc_dummy)(struct dummy_heap_mem *h_mem, os_size_t size);
    void *(*k_aligned_alloc_dummy)(struct dummy_heap_mem *h_mem, os_size_t align, os_size_t size);
    void (*k_free_dummy)(struct dummy_heap_mem *h_mem, void *mem);
    void *(*k_realloc_dummy)(struct dummy_heap_mem *h_mem, void *mem, os_size_t newsize);
    void (*k_deinit_dummy)(struct dummy_heap_mem *h_mem);
    os_err_t (*k_mem_check_dummy)(struct dummy_heap_mem *h_mem);
#ifdef OS_USING_MEM_TRACE
    os_err_t (*k_mem_trace_dummy)(struct dummy_heap_mem *h_mem);
#endif
    os_size_t (*k_ptr_to_size_dummy)(struct dummy_heap_mem *h_mem, void *mem);
    void                  *header_dummy; /* Pointer to current memory's start address */
    struct dummy_heap_mem *next_dummy;   /* Pointer to next memory's heap_mem object */
    os_size_t              mem_total_dummy;
    os_size_t              mem_used_dummy;
    os_size_t              mem_maxused_dummy;
    dummy_semaphore_t      sem_dummy;
    enum os_mem_alg        alg_dummy;
};

二、堆结构体

struct dummy_heap
{
    struct dummy_heap_mem *h_mem_dummy;
    uint8_t                object_inited_dummy;
    char                   name_dummy[OS_NAME_MAX + 1];
    os_list_node_t         resource_node_dummy; /* Node in resource list */
};
typedef struct dummy_heap dummy_heap_t;
