kandi X-RAY | any_function Summary
any_function.h is a single header public domain utility library for C++11. It is intended to serve as a functional counterpart to the std::any, by providing a single, concrete class any_function which can receive almost any callable object, from function pointers to lambdas to instantiations of std::function. This library is still under development and its API and implementation details are subject to change.

Answered 2021-May-23 at 18:42When using multiprocessing, the library spawns multiple different processes. Each process has its own address space. This means that each of those processes has its own copy of the variable, and any change in one process will not reflect in other processes.
In order to use shared memory, you need special constructs to define your global variables. For pathos.multiprocessing
