Whatever you can call it), and also will not be reused. ![]() ![]() You might have guessed it: this is achieved by the capture list. A lambda function is a short snippet of code that: Isn't worth naming (unnamed, anonymous, disposable, etc. Luckily, all these things fit nicely together: You can provide state to the closure objects, by giving them member variables, so the member function details make sense. I left a few details untouched, such as what the capture list is and how it works, details about several closure type member functions that would make only sense if the closure has member variables, and how to solve problems that would require function objects with state. ![]() In the last post of my series about (relatively) new C++ features I introduced lambda expressions, which define and create function objects on the fly. 5 Returning to closure member functions.They can be defined at any point and are not tied to a function name. 2.1 Capture by value versus capture by reference which makes it more apparent that something is wrong with the type of the default callable, namely the lambda. Registering the callback simply requires referencing the function pointer of the static member function: registercallback(&Client::func) Lambda Functions Lambda functions are also called anonymous functions. If the function call operator template is a static member function template, then the value returned by any given specialization of this conversion function.
