Questions tagged [bind]
This tag means different things in different contexts: consider using less ambiguous tags instead. Common meanings include: the bind function in socket programming; binding to naming contexts; the bind method in jQuery; BIND the DNS server (named), . For boost::bind in C++, use [boost-bind]. Do not use this tag just to say that you're binding something to something else.
