Thread-"signalSignal is an event that occurs when UNIX and Linux systems respond to certain conditions. The process that receives the signal takes some action accordingly.Raise generation represents the generation of a signalCatch capture indicates
The pause function of the pause function suspends the process that calls it until any message arrives . The calling process must be able to handle the signal being served, otherwise the default deployment of the signal will occur. int pause (void),

On UNIX, there are many communication methods between processes. In the early days, there were unknown pipelines, famous pipelines and signals, and later I introduced IPC objects
Linux Signal Set1. Concept of Signal SetA signal set is a data type that can represent multiple signals. sigset_t set; set is a signal set.Since it is a set, you need to add/Delete the set.Int sigemptyset (sigset_t * set); empty the setInt
All threads share the same signal processing methodThe main thread sets the processing mode of the SIGINT signal in order to capture, then all the secondary threads share this processing, and if one of the threads changes the way the signal is

According to POSIX, asynchronous (external) signals are sent to the entire process.
All threads share the same setting, that is, the thread disposal method set

Signal (2) sigaction Function
The sigaction function is used to check or modify the processing actions associated with the specified signal. This function replaces the signal function.
