Dear list,
I’m looking at using the STREAM socket to interface with some plain old TCP
clients, however, there seems to be two things I’m missing:
1. How do I send a message to a client first? Once the client sends a message I
can get the identity frame and use that to reply. How do I send a message
before receiving any data?
ZMQ_STREAM is like ROUTER. In my understanding and small experience, you
cannot.
2. Closing sockets. I see in the docs that a socket can be closed by sending
the identity frame followed by a zero length frame. However, this does not seem
to be working.
I’m expecting to successfully read 0 bytes from the TCP socket meaning that the
connection was actively closed, and no error codes. Instead by TCP socket recv
blocks forever. The only way I can get this to happen is to close the ZMQ
socket, which is not possible when I am using bind and talking to multiple TCP
clients.
Cheers,
Matt
