Why callback functions needs to be static when declared in class
- by Dave17
I was trying to declare a callback function in class and then somewhere i read the function needs to be static but It didn't explain why?
#include <iostream>
using std::cout;
using std::endl;
class Test
{
public:
Test() {}
void my_func(void (*f)())
{
cout << "In My Function" << endl;
f(); //Invoke callback function
}
static void callback_func()
{cout << "In Callback function" << endl;}
};
int main()
{
Test Obj;
Obj.my_func(t.callback_func);
}
