Timer.3 - Binding arguments to a handler - 1.66.0 - Boost

WebI have implemented a class that provides portable one-shot or periodic timers. The API provides a way to schedule one or more timer callbacks to fire some number of milliseconds in the future, and optionally fire again every so many milliseconds. The API returns an ID which can be used later to see if the timer still exists, or destroy it. http://wiki.ros.org/roscpp/Overview/Timers

WebThese are the top rated real world C++ (Cpp) examples of boost::asio::deadline_timer extracted from open source projects. You can rate examples to help us improve the quality of examples. Programming Language: C++ (Cpp) Namespace/Package Name: boost::asio. Class/Type: deadline_timer. Examples at hotexamples.com: 30. WebAs you can see, the boost::bind () function is used to associate the extra parameters with your callback handler. The deadline_timer::async_wait () function expects a handler function (or function object) with the signature void (const boost::system::error_code&).

WebClass timer measures elapsed time. It is generally useful for minor timing tasks.
