Detailed Description

template<typename... FunctionArgs>
class anonymous_namespace{libloadplay.cpp}::Callback< FunctionArgs >

Implements a recursion safe std::function wrapper.

The purpose is to prevent recursive calls of a callback function handle, in cases when a callback function performs actions that cause a successive call of the callback function.

To avoid having to return a value when a successive function call occurs only functions returning void are valid callback functions.

This is not thread safe.

Template Parameters

FunctionArgs

The argument types of the callback function
