UNIX: Is there an opposite for the SIG_IGN?

Question

Hello I am making a program in c and I need to make a signal(SIGINT, SIG_IGN); but I need then at a certain point in the code to stop ignoring those signals, is there something like that?

Answer 1

You can set a signal to use its default signal handling by passing SIG_DFL to signal.

signal(SIGINT, SIG_DFL);
