The spawn()
function is a high-level wrapper over the Boost.Coroutine library. This function
enables programs to implement asynchronous logic in a synchronous manner,
as illustrated by the following example:
boost::asio::spawn(my_strand, do_echo); // ... void do_echo(boost::asio::yield_context yield) { try { char data[128]; for (;;) { std::size_t length = my_socket.async_read_some( boost::asio::buffer(data), yield); boost::asio::async_write(my_socket, boost::asio::buffer(data, length), yield); } } catch (std::exception& e) { // ... } }
