From ff93f54653d099bddfed34a342906a3546e70496 Mon Sep 17 00:00:00 2001 From: Martin Sustrik Date: Sun, 12 Jun 2011 15:24:08 +0200 Subject: ZMQ_FILTER socket option added This option is a performance tweak. In devices XSUB socket filters the messages just to send them to XPUB socket which filters them once more. Setting ZMQ_FILTER option to 0 allows to switch the filtering in XSUB socket off.
