How to use events in C/C++

Question

How to work with events and listeners

Answer 1

C has a signal.h library that allows to handle signals. Signals are a bit like events in JavaScript, you assign a function to a signal handler that will be executed once the signal is sent. Signals are not as powerful though and are mostly used e. g. for gracefully exiting a program when the user terminates it (by sending an abort or kill signal)
