Readline: Get a new prompt on SIGINT

Question

I\'ve got code similar to the following, using readline:

#include 
#include 
#include 
#include          


        

Answer 1

Call rl_clear_signals().

This will disable the signal handlers libreadline installed. The one that handles SIGINT is responsible for the observed behaviour of restoring the prompt.
