signal_set::signal_set (4 of 4 overloads)

Construct a signal set and add three signals.

signal_set(
    asio::io_context & io_context,
    int signal_number_1,
    int signal_number_2,
    int signal_number_3);

This constructor creates a signal set and registers for three signals.

io_context: The io_context object that the signal set will use to dispatch handlers for any asynchronous operations performed on the set.
signal_number_1: The first signal number to be added.
signal_number_2: The second signal number to be added.
signal_number_3: The third signal number to be added.

This constructor is equivalent to performing:

asio::signal_set signals(io_context);
signals.add(signal_number_1);
signals.add(signal_number_2);
signals.add(signal_number_3);
