Pthread 中的信号处理
pthreads 的 man 页面提到：
POSIX.1 also requires that threads share a range of other attributes
(i.e., these attributes are process-wide rather than per-thread):
...
- signal dispositions

“信号处置”是什么意思？

What do "signal dispositions" mean?

信号处理是指传递信号时进程采取的操作。每个信号都有一个倾向。有默认值。
来自 signal(7)：
Signal Dispositions Each signal has a current disposition, which determines how the process behaves when it is delivered the signal. [Dispositions are:] Term Default action is to terminate the process. Ign Default action is to ignore the signal. Core Default action is to terminate the process and dump core (see core(5)). Stop Default action is to stop the process. Cont Default action is to continue the process if it is currently stopped. [...] The signal disposition is a per-process attribute: in a multithreaded application, the disposition of a particular signal is the same for all threads.I signal disposition is the action a process takes when a signal is delivered. Each signal has a disposition. There are defaults.

也可能存在调用信号处理程序时信号被屏蔽的问题，等等。
The disposition of a signal is how it is handled.
There can also be issues of signals masked while the signal handler is called, and so on.
这意味着 Unix 进程如何对信号做出反应。请参阅
signal(7)。This means how Unix process reacts to signals. See
