efl.ecore.FdHandler
Class¶efl.ecore.
FdHandler
(fd, int flags, func, *args, **kargs)¶Bases: object
func
will be called during the execution of main_loop_begin()
when the file descriptor is available for reading, or writing, or both.
When the handler func
is called, it must return a value of
either True or False (remember that Python returns None if no value
is explicitly returned and None evaluates to False). If it returns
True, it will continue to monitor the given file descriptor, or if
it returns False it will be deleted automatically making any
references/handles for it invalid.
