Question

First look at these templates.

struct INIWindows{
    inline int GetInteger(){
        return 100;
    }
};

struct INILinux{
    inline int GetInteger(){
        return 120;
    }
};

template <class Reader>
class SettingsManager : public Reader{

};

Edit: Addendum because it was not clear what i was doing.

int main(){
    SettingsManager<INIWindows> Settings;
    printf("Integer Reads %i\n",Settings.GetInteger());
    system("pause");
    return 0;
}

Is my understanding correct that this will result in SettingsManager having an inline function called get integer that will then be inlined properly by the compiler?

Yes, your understanding is correct. Your methods are going to be placed in the SettingsManager class, without a virtual dispatch, because the base classes (INIWindows and INILinux) do not have virtual methods.

The inline keyword is only a command for the compiler to try to inline the method – nothing else. It is free not to do it.
