Detailed Description
FileHandle based I/O read/write event.An IOEvent is signaled, whenever the FileHandle handle becomes readable or writable. The type of event is specified using the events mask with values from EventFlags.
There are two types of flags:
- Event flags (Read, Prio, Write) specify the type of event. The callback will be called whenever one of the specified events occurs on the filehandle
- Error flags (Hup, 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.
