boost::asio::deadline_timer cancel and expires_from_now
Hi, Is it necessary to call the timer.cancel() before timer.expires_from_now? I think it is not just unnecessary, it will be a bug to call the timer.cancel() before timer.expires_from_now, I think that will run the cancel if the previous timer is not expired, is it correct? Thank you
Hi! The documentation http://www.boost.org/doc/libs/1_64_0/doc/html/boost_asio/reference/basic_wai... stands that any pending operations will be cancelled, just like calling timer.cancel(). Have in mind that the handler for the cancelled operation will be called with error_code set to boost::asio::error::operation_aborted.
