An IOEvent is signaled, whenever the FileHandle \a handle becomes readable or writable. The
type of event is specified using the \a events mask with values from EventFlags.
- \fixme Implement error/EOF handling
+ There are two types of flags:
+
+ \li Event flags (\ref Read, \ref Prio, \ref Write) specify the type of event. The
+ callback will be called whenever one of the specified events occurs on the filehandle
+ \li Error flags (\ref Hup, \ref Err) specify some type of error condition on the
+ filehandle. If you specify an error flag when registering the event, the error condition
+ will be passed to the callback, otherwise an ErrorException or HangupException will be
+ thrown.
