struct bb {
unsigned enter_water_erred: 1;
unsigned drain_erred: 1;
unsigned overflow_erred: 1;
unsigned door_lock_erred: 1;
unsigned rise_temp_erred: 1;
unsigned abnormality_temp_erred: 1;
unsigned sensor_erred: 1;
};
union {
unsigned char byte;
struct bb bit;
}f10;
看到一程序，里面有用这样的表达式：
f10.bit.drain_erred = 0;
f10.bit.door_lock_erred = 1;
f10.byte = 0;
但是我没找到头文件，因此我定义了上面那样的，请指点一下，我这样定义是否正确，如果正确，有没有更好的定义方法？？
谢谢 |
