Boost C++ Libraries

...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

basic_signal_set::basic_signal_set (6 of 8 overloads)

Construct a signal set and add two signals.

template<
    typename ExecutionContext>
basic_signal_set(
    ExecutionContext & context,
    int signal_number_1,
    int signal_number_2,
    typename constraint< is_convertible< ExecutionContext &, execution_context & >::value, defaulted_constraint >::type  = defaulted_constraint());

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

Parameters

context: An execution context which provides the I/O executor that the signal set will use, by default, to dispatch handlers for any asynchronous operations performed on the signal set.
signal_number_1: The first signal number to be added.
signal_number_2: The second signal number to be added.

Remarks

This constructor is equivalent to performing:

boost::asio::signal_set signals(context);
signals.add(signal_number_1);
signals.add(signal_number_2);
