I know about http://sourceforge.net/projects/loki-lib/ but with boost::bind this can be much simpler: https://github.com/RSATom/finally_execute/blob/master/README
I've used this in many of my projects, and found it very usefull....
don't understand, why this simple solution does not contributed already to Boost by someone else... :)
Hi,
have you take a look at Boost.ScopedExit? Yes, but I think it's give too "dirty" code. And I don't like macros in C++ era :)
Btw, in C++11 era (i.e., lambdas) no macros needed: void world::add_person(person const& a_person) { bool commit = false; persons_.push_back(a_person); scope_exit on_exit1([&commit, this](void) { // Use C++11 lambda. if(!commit) persons_.pop_back(); // `persons_` via captured `this`. }); // ... commit = true; } http://www.boost.org/doc/libs/1_51_0/libs/scope_exit/doc/html/scope_exit/alt... --Lorenzo
