こんな人生が嫌になった

typedef struct image_t {
    int width;
    int height;
    char *px;
} image_t;

int get_image_size(image_t *img)
{
    return img->width * img->height;
}

int init_image(image_t *img,
               int width,
               int height)
{
    img->width = width;
    img->height = height;
    img->px = malloc(get_image_size(img));
    return img->px != NULL;
}

↓ 微妙にC++ wayに近づけた結果がこれだよ

class Image {
    int width;
    int height;
    char *px;

public:
    int size()
    {
        return width * height;
    }

    void init(int width,
              int height)
    {
        width = width; ← オワタ
        height = height;
        px = malloc(size());
    }
};

こんな人間失格の僕にもValgrindだけは普段と変わらぬ素振りで声をかけてくれる：

もう俺の人生には水とValgrindだけあればいいや... 食欲無いし...
それとVSのデバッガは一刻も早く，関数の返り値を表示できるようになること*1．
