The signal binding mechanism simply means that the external signal is converted to an internal IO event for processing. Since the signal capture function is globally bound, there is no way to bind the IO event and file descriptor as an IO event, and

Libevent, as the network IO library in unix/linux, efficiently integrates IO events, Timeout events, and signal events. This article mainly describes the ins and outs of Integrated signal events. First paste the code of the client application signal

Pthread_kill: Don't be scared by the name. pthread_kill is not a kill, but a signal sent to the thread. Do you still remember signal? Most of the default actions of signal are to terminate the running of processes. Therefore, we only need to use

Recently encountered a process abruptly exiting the issue, because there is no registration signalhandler so no signal is captured.However, from the log to see the status of Init Waitpid returned to 0x008b, before the status is not very

The use of signaling mechanisms in multi-threaded Linux is fundamentally different from the use of signaling mechanisms in the process. In the process environment, the signal processing is to register the signal processing function, when the signal
