This second ref-count increase makes sure that `s` lives until all messages that use it have been sent. Once 0MQ sends all the messages and it doesn't need the buffer of s, 0MQ will call ``Py_DECREF(s)``. Parameters ---------- data : object, optional any object that provides the buffer interface will be used to construct the 0MQ message data. track : bool [default: False] whether a MessageTracker_ should be created to track this object. Tracking a message has a cost at creation, because it creates a threadsafe Event object. copy : bool [default: use copy_threshold] Whether to create a copy of the data to pass to libzmq or share the memory with libzmq. If unspecified, copy_threshold is used. copy_threshold: int [default: zmq.COPY_THRESHOLD] If copy is unspecified, messages smaller than this many bytes will be copied and messages larger than this will be shared with libzmq. cCs |j|ƒS(N(tget(tselftkey((s.lib/python2.7/site-packages/zmq/sugar/frame.pyt __getitem__1scCstddƒ|jdƒS(s”The RADIO-DISH group of the message.
