[Solved] *this emulation in standalone functions [closed]

by


Here’s a possible solution: Use the same name, just at different scopes.

#include <iostream>

#define LOG(x) do { log() << (x) << '\n'; } while(false)

std::ostream & log() { return std::clog; }

struct Identifier
{
    std::ostream & log() { return ::log() << id << ": "; }
    int id;

    explicit Identifier(int n) : id(n) {}
};

struct SomeClass : Identifier
{
     SomeClass() : Identifier(123) {}

     void helloFunc()
     {
         LOG("hello"); // will print to cout: "123hello"
     }
};

int main()
{
    LOG("in main");
    SomeClass().helloFunc();
}
