Question

我有以下结构

typedef struct Body
{
    struct Body *next;
    struct Body *prev;
    SDL_Rect value;
} Body;

我想用以下

分配身体的新部分

void init_body(Body **out_body, SDL_Rect *rect, Body *prev)
{
     struct Body* new_body = malloc(sizeof(struct Body));
     new_body->next = NULL;
     new_body->prev = prev;
     new_body->value = *rect;
     *out_body = new_body;
}

然而（我在窗户上）记忆博士正在提出以下抱怨：

我如何清理此内存泄漏？

创造的逻辑

void create(SDL_Renderer *renderer, Snake *snake) {
    SDL_Rect r = SDL_CreateRect(10, 10, 100, 100);

    snake->size = 1;
    snake_init_body(&snake->body, &r, NULL);
    snake->surf = SDL_CreateRGBSurface(0, 10, 10, 32, 0xFF000000, 0x00FF0000, 0x0000FF00, 0x000000FF);
    SDL_FillRect(snake->surf, NULL, 0xAAAAAAFF);
    snake->texture = SDL_CreateTextureFromSurface(renderer, snake->surf);
}

DOH最后需要释放（我从未这样做过）：

void snake_free(Snake *snake)
{
    struct Body *abody = snake->body;

    while (abody != NULL)
    {
        if (abody->next == NULL)
        {
            free(abody);
            break;
        }
        else
        {
            abody = abody->next;
        }

        if (abody != NULL)
            free(abody->prev);
    }
}

您是否正在经历某个时刻并释放列表中的每个节点？
