	)

constructor, relates file activity on fd to an event or callback

Parameters:

	pev	event to trigger when activity on fd
	fd	filedescriptor opened appropriately
	flag	ORing of ix_fd_type_e
	cb	when supplied, cb is called when activity on fd; if cb returns < 0 the ix_fd_t object is internally deleted do not free it externally
