Presentation at Oslo C++ Users Group on Friday, 14 June

On Friday, 14 June (a week from this coming Friday), I'll be giving a talk in Oslo for the Oslo C++ Users Group. Admission is free. The topic I'll be addressing is:

Lambdas vs. std::bind in C++11 and C++14

C++ developers have long had a need to bind functions and arguments together for a later call. This is what makes it possible to invoke member functions on objects inside STL algorithms. The same technology can be used to create custom callback functions and to adapt function interfaces to different calling contexts.

In C++98, such binding was accomplished via std::bind1st and std::bind2nd. TR1 added std::tr1::bind, which was promoted to std::bind in C++11. But C++11 also introduced lambda expressions, and they’re slated to become even more powerful in C++14. That means that there are now two mechanisms in C++ for binding functions to arguments for later calls: std::bind and lambda expressions.In this talk, Scott examines the pros and cons of each approach, comparing them in terms of expressiveness, clarity, and efficiency, and he comes to the conclusion that one should almost always be used instead of the other. But which one?

This presentation assumes a basic familiarity with std::bind and C++11 lambda expressions.
For time and location, consult the talk announcement.

I hope to see you there!

Scott
