Hi,
After sending a message using send(..) the message should be deallocated, as documented in api_thread.hpp(see the code snip bellow).
If I resend the same message once more the buffer is sent but the arrived message size is 0.
There is the method present() which requires to call flush(), which I could use.
But, I don't know if this is the indented behaviour for send(), since in this case
you are sending "useless" data.
The same behaviour is noticed for v0.5 and v0.6
<api_thread.hpp>
// Send a message to specified exchange. 0MQ takes responsibility
// for deallocating the message. If there are any pending pre-sent
// messages, flush them immediately. If 'block' parameter is true
// and there are no queues bound to the exchange, execution will be
// blocked until a binding is created. Returns true is message was
// successfully enqueued, false if it was not send because fo pipe
// limits.
ZMQ_EXPORT bool send (int exchange_, message_t &message_, bool block_ = true);
</api_thread.hpp>
Thanks in advance,
Ayman
