Cast pointer to member function to normal pointer

Question

Currently I have a class of this kind, shortened for simplicity:

class MyClass {
    public: 
        MyClass();
        void* someFunc(void* param);
}
         


        

Answer 1

class MyClass 
{
public: 
    MyClass();
    void* someFunc(void* param);
};

void* callback(void*)
{
    MyClass instance;
    instance.someFunc(0 /* or whatever */);
}

void foo()
{
    secondFunc( 1, 2, callback);
}
