Furthermore, @libevent also support callbacks due - * to signals or regular timeouts. - * - * @eventxx is a simple, direct, one-header inline C++ wrapper for @libevent. - * Yes, it's just one header file, so if you want to use it you can just copy - * the file to your project and you are set (well, you'll need to link to - * @libevent too ;). - * - * It's designed to be as close to use to @libevent (without compromising - * modern C++ programming techniques) and efficient (since all implementation - * is trivial and inline, theoretically, it imposes no overhead at all) as - * possible. - * - * Please, visit the @eventxx website for the latest version of this - * documentation. - * - * You can always get the current - * release from the - * release - * directory or grab the - * most up to date - * sources from the darcs repository. - * - * You can also take a look the the darcsweb interface to see - * the latest - * changes online or subscribe to its - * RSS - * feed to follow the development. - * - * - * @section Usage - * - * You probably should read @libevent documentation to get started or at least - * just for reference, although @eventxx is pretty simple so you can jump right - * into the \ref Example section (or the example list) and write a working - * program without much trouble. - * - * This wrapper was designed to be used just like @libevent, but with C++ style - * syntax sugar (or poison, depends on your point of view ;) and goodies. The - * main difference to libevent is you always have to instance a - * eventxx::dispatcher to get an event loop. There is no implicit global event - * loop. This adds just an extra line of code for single threaded applications - * and makes things much more simpler, so I hope nobody complains about it ;). - * See eventxx::dispatcher documentation for more details. - * - * You can use use the same plain functions callbacks @libevent use or the other - * kind of function objects (see @ref events section for details on event - * types). - * - * @eventxx uses @ref exceptions to report errors. All functions have exception - * specifications, so it's easy to find out what to expect. See @ref exceptions - * section for more detail. - * - * A @c timespec abstraction is provided as eventxx::time for convenient - * argument passing. Even more, it's a @c timespec itself, with some convenient - * methods for accessing the attributes with pritier names. And even more, - * @eventxx is such a direct mapping that all eventxx::event's are @libevent - * event structs too, so theoretically you can pass a eventxx::event to - * @libevent C functions without much trouble. eventxx::dispatcher is the only - * class that is not derived from @libevent struct (@c event_base) because this - * struct it's not defined on the libevent header (just declared). - * - * Maybe you shouldn't know this implementation details to keep the abstraction, - * but this is a basic design goal of this wrapper so there is not much chance - * that this changes in the future (but use this knowledge with care, you have - * been warned ;). - * - * - * @section Example - * - * @code - * #include - * #include - * #include - * - * struct handler - * { - * eventxx::dispatcher& d; - * int i; - * handler(eventxx::dispatcher& d): d(d), i(0) {} - * void operator() (int signum, eventxx::type event) - * { - * if (i < 5) std::cout << "keep going...\n"; - * else - * { - * std::cout << "done!\n"; - * d.exit(); - * } - * } - * }; - * - * void sighandler(int signum, short event, void* data) - * { - * int& i = *static_cast< int* >(data); - * std::cout << ++i << " interrupts, "; - * } - * - * int main() - * { - * eventxx::dispatcher d; - * handler h(d); - * eventxx::csignal sigev(SIGINT, sighandler, &h.i); - * eventxx::signal< handler > e(SIGINT, h); - * d.add(sigev); - * d.add(e); - * d.dispatch(); - * return 0; - * } - * @endcode - * - * You can see more examples on the test directory of the distribution or on the - * examples related page. - * - * - * @section Status - * - * This library has not been widely used yet, but it's used in some serious - * projects, so I think it's moderately stable now. The library has no support - * for buffered events yet, but patches are welcome. It doesn't support the - * HTTP stuff, and probably never will because that has nothing to do with - * event handling. - * - * @libevent had a memory leak before version 1.3b (before 1.2 it didn't even - * had a way free that memory, from version 1.2 to 1.3a, if you tried to free - * the memory the program @c abort() because a failed assertion). Because of - * that, there is a way to disable the @link eventxx::dispatcher::~dispatcher() - * dispatcher destructor @endlink (which calls the inexistent/broken - * @c event_base_free() function). So if you use a @libevent version previous - * to 1.3b, you have to compile your programs defining the - * @c EVENTXX_NO_EVENT_BASE_FREE macro. - * - * If something is broken it would be really easy to fix because @eventxx is - * just a simple wrapper around @libevent. So, please try it out, and if you - * have any problems, drop me an - * e-mail and and I'll fix it ASAP (or provide a patch and you will be my - * best friend ;). - * - * If you use this library, please drop me an e-mail with your thoughts, or - * simply saying "I use it", so I can keep track of how many people really use - * it. - * - * @author Leandro Lucarella - * - * @version 0.6 - * - * @par License - * This program is under the BOLA license (see - * http://auriga.wearlab.de/~alb/bola/ for more details or read the - * LICENSE - * file itself, it's very short and it basically says it's Public Domain). - * - */ - -/** @example c-way.cpp - * - * This is a simple example illustrating the usage with C-like callback - * functions. - */ - -/** @example functor-way.cpp - * - * This is a simple example illustrating the usage with function object - * callbacks. - */ - -/** @example wrapped-functor-way.cpp - * - * This is a simple example illustrating the usage with an arbitrary member - * function as an event handler callbacks. - */ - -/** @example mixed-way.cpp - * - * This is a simple example illustrating the usage with a mix of C-like callbacks - * and function object callbacks. - */ - -/** @example bench.cpp - * - * This is a benchmark example, extracted from libevent and ported to eventxx. - */ - -/** @example prio-test.cpp - * - * This is a priority usage example. - */ - -/** @example test-time.cpp - * - * This is a timer usage example ported from libevent. - */ - -/** @example test-eof.cpp - * - * This is some kind of test of EOF ported from libevent. - */ - -/** @example test-weof.cpp - * - * Another test of EOF ported from libevent. - */ - -/** @example trivial.cpp - * - * This is the most trivial example. - */ - /** * Namespace for all symbols libevent C++ wrapper defines. */
