Folks;
We have test software that is testing the request reply
pattern. We are doing failure testing. The failure testing involves killing and
restarting the server. We have code in the requester that "attempts" to do a
reconnect to the server. However, after the reconnect, the subsequent send
calls always fail and ZeroMQ reports "Operation cannot be accomplished in
current state". Is there a way to "reset" a request socket and clear this
condition?
Thanks
Rick

Hi,
zmsg_ function can be used to send/receive any kind of data in czmq.

Hello,
I'm using czmq to transfer serialized objects in char arrays. The serialized
data may contain nulls, so processing with c-string oriented functions Is a
problem. So using zstr_recv(void*) doesn't work for me as it returns a char*
with no way to identify the length of the array.
I thought I might dip into the zmq calls directly so I can use zmq_recv(void*
source, void* buf, size_t len, int flags), as it returns the number of bytes
copied into the buffer. But my sockets are created with zsock_new(...), so I'm
not sure about the compatibility of these calls. Am I on the right track with
this, and can someone offer some advice on how to proceed? I did try just
putting my zsock_t* into the zmq_recv call, but it just returns -1 even though
zpoller_t reports that there is data available on the socket.
Thanks -
Brian.
