[zeromq-dev] zmq_msg_init_data with zero deallocation function

[Ilja Golshtein]

Hello!

According to zmq_msg_init_data manual
==
       int zmq_msg_init_data (zmq_msg_t *msg, void *data, size_t size, zmq_free_fn *ffn, void *hint);
==
ffn is optional ("If provided, the deallocation function ffn shall be called once the data buffer is no longer required by 0MQ").

How does the thing work if ffn is not provided?

Is the code
==
zmq_msg_t msg;
zmq_msg_init_data (&msg, (void *)"something", 9,  NULL, NULL);
==
valid?

Thanks.
