#define APP_ERROR(fmt, ...) printf("[ERROR][%s,%d]: " fmt "\n", __FUNCTION__, __LINE__, ##__VA_ARGS__)
#define APP_TRACE(fmt, ...) printf("[TRACE][%s,%d]: " fmt "\n", __FUNCTION__, __LINE__, ##__VA_ARGS__)
#define APP_DEBUG(fmt, ...) printf("[DEBUG][%s,%d]: " fmt "\n", __FUNCTION__, __LINE__, ##__VA_ARGS__)The effect is as follows
