[Boost-users] bind/function: composition

I often tend to have interfaces which take a boost::function that is to be called when an event occurs. Quite often I need make two separate function calls as response to one event. In these cases I usually solve the problem using the following technique: void foo(); void bar(); void call_two(const boost::function& one, const boost::function& two) { one(); two(); } boost::function on_event = boost::bind(&call_two, boost::bind(&foo), boost::bind(&bar)); Is there any other way to acheive this, beside having to redeclare and define a function such as call_two? It seems quite easy to define something like: template void nullary_compose boost::function& one, const boost::function& two); template void nullary_compose boost::function& one, const boost::function& two, const boost::function& three); ... Is anybody else interested in seeing such templates in boost? Best Regards, Johan Torp -- System Developer TouchTable AB Tel: +46 (0)31 773 68 12 johan.torp@touchtable.se
