Detailed Description

There are many ways to specify how to handle an event.

You can use use the same plain functions callbacks (see eventxx::cevent, eventxx::ctimer and eventxx::csignal) like in C or the other kind of more advanced, stateful function objects (see eventxx::event, eventxx::timer and eventxx::signal templates). The former are just typedef'ed specialization of the later.

A member function wrapper functor (eventxx::mem_cb) is also included, so you can use any member function (method) as an event handler.

Please note that C-like function callback take a short as the type of event, while functors (or member functions) use eventxx::type.

All events derive from a plain class (not template) eventxx::basic_event, one of the main utilities of it (besides containing common code ;) is to be used in STL containers.

Please see each class documentation for details and examples.

Typedef Documentation

typedef void(* eventxx::ccallback_type)(int, short, void *)

C function used as callback in the C API.

typedef eventxx::event< ccallback_type > eventxx::cevent

Shortcut to C-style event.

Examples:

test-eof.cpp.

typedef eventxx::signal< ccallback_type > eventxx::csignal

Shortcut to C-style signal handler.

typedef eventxx::timer< ccallback_type > eventxx::ctimer

Shortcut to C-style timer.

Examples:

test-time.cpp.

Enumeration Type Documentation

enum eventxx::type

Type of events.

There are 4 kind of events: eventxx::TIMEOUT, eventxx::READ, eventxx::WRITE or eventxx::SIGNAL. eventxx::PERSIST is not an event, is an event modifier flag, that tells eventxx that this event should live until dispatcher::del() is called. You can use, for example:

 eventxx::event(fd, eventxx::READ | eventxx::PERSIST, ...);

Enumerator:

TIMEOUT	Timeout event.
READ	Read event.
WRITE	Write event.
SIGNAL	Signal event.
PERSIST	Not really an event, is an event modifier.
