Script to handle interruption signal in c++ while also closing a log (Although it is unnecessary)

syslog.cpp

#include <iostream>
#include <syslog.h>
#include <string>
#include <csignal>

void signal_handler(int signal_num)
{
	std::cout << "The interrupt signal is (" << signal_num << "). \n";

	// terminate program
	closelog();
	std::cout << " Closed log " << std::endl;
	exit(signal_num);
}

int main()
{
	openlog("Logs", LOG_PID, LOG_USER);
	std::string msg;
	int i = 0;
	//openlog("ConnectivityManager", LOG_PID, LOG_USER);
	signal(SIGINT, signal_handler);
	while (true)
	{
		syslog(LOG_INFO, "Start logging");
		syslog(LOG_DEBUG, "oh yeah");
		++i;
		if (i == 10)
		{
			//raise(SIGINT);
		}
	}
	//closelog();
}
