chsvthrd\chsv_thread_local_1.cpp

Demonstrates a usage and an effect of the chsv_thread_local macro.

#include <iostream>
#include <string>
#include <thread>
#include <mutex>
#include "chsvthrd.h"
 
chsv_thread_local(unsigned int, rage) = 1;
std::mutex cout_mutex;
 
void increase_rage(const std::string& thread_name)
{
    ++rage;
    std::lock_guard<std::mutex> lock(cout_mutex);
    std::cout << "Rage counter for " << thread_name << ": " << rage << '\n';
}

        std::cout << "Rage counter for main: " << rage << '\n';
    }
 
    a.join();
    b.join();
 
    return 0;
