[zeromq-dev] Is there a way to remove all subscriptions from a SUB socket in one operation?

[Martin.Belanger at dell.com]

Hi,

Let's say I've made several subscriptions using zmq_setsockopt(sock,  ZMQ_SUBSCRIBE, ...) and later I want to remove all these subscriptions. 

I know I can remove each subscription by successively invoking zmq_setsockopt(sock, ZMQ_UNSUBSCRIBE, ...), but I was just wondering if there was a quick way to remove all subscriptions with one zmq call? 

Thanks,
Martin
