I removed the signal mask between line 18 ~23.
So the signal is not ignored, it should be captured by the Signal handler.
Now I run the program, it goes into endless loop, as in your comments. How

signal
三点turn的时候，一开始signal右然后head check，靠右停下，然后signal左，再HC，
左转停下后，还需要signal再倒退吗？如果需要再signal，那是打左的signal还是右的
signal呢？
问题二，当uphill或downhill打了右的signal后pull over停在那里后，灯要一直亮着继续完成动作还是一直打着灯完成接下来的轮子靠curb的动作呢？

发帖数: 674 | 26 I install a signal handler for a process.
The handler will catch all the signals except 9 and 23, and do nothing but
"print", and so on.
I found out that that: When the process receive the same signal for a second
time, the handler will not function anymore. And default action for that
signal will take effect.
I can't find any book mention such problem.
Is this a bug in my program, or it is the way that signal works? |

According to POSIX, the behaviour of a process is undefined after it
ignores a SIGFPE, SIGILL, or SIGSEGV signal that was not generated by
the kill(2) or the raise(3) functions. Integer division by zero has
undefined result. On some architectures it will generate a SIGFPE signal.
(Also dividing the most negative integer by -1 may generate SIGFPE.)
Ignoring this signal might lead to an endless loop. |

今天路过这样一个路口。我自西向东走，准备向北面左转。一共有三条lane，分别是左
转，左转+直行，右转，我是最左面lane上的第一辆车。信号灯是绿色非箭头，于是我
稍微向前开出白线，然后停下等对面的直行车辆。对面有几辆直行车，还有一辆右转车
，他们都在路口前面，速度很慢。由于距离比较近，我就决定等他们过去后再转，结果
这时后面的车开始horn，我一紧张就硬着头皮转过去了。转的时候发现直行车没有过来
，而且那辆右转车明显在yield我。
回来仔细想了想，猜测对面的车可能这时候是红灯，但是为什么我们的信号灯不是左转
箭头灯呢。google map了一下看到有个 3-way signal的标志，应该是和这个有关吧。
google了一下还是没搞太明白。请教一下大家给解释一下3-way signal的具体含义，还
