C++ :: How To Access Class Member And Methods From Static Method (signal Handler)

I am writing my program on C++ language. I have one promblem. I need to set signal handler for my process. As the signal is related with the process on system level I have faced the problem.

My program consists several classes. They are connected together. But it doesn't metter in this case. The problem is that I need to access to member and methods of the class from my signal handler. For instance , I have class named Foo at it has some members and methods.

So from my handler I need to call its function and change members.

I understand that compiler should know that this class instances will exist during all program execution.

I have tried to set static member class Foo instance in another class , but this didn't solve the problem.

What is correct approach to do this. How to correctly implement signal handling in such case.

Here is example of my code

class MyContainer{
private:
std::vector<Foo> container;
public:
int removeFromContainer(Foo* aFoo) {
