Re: [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));

#include boost::function on_event = (boost::lambda::bind(&foo), boost::lambda::bind(&bar)); // Johan (Nilsson)
