What's a good manner to use SIGINT for killing app in C++? -


i'm developing server application , want use sigint killing application. although know 2 ways, i'm not sure way kill application.

are there better ways handle siging?

int main() {  startserver();   1. while(true) {sleep(3); if(sigflag) break;}  2. std::getline(std::cin, param);   stopserver();  return 0; } 

#include<stdio.h> #include<signal.h> #include<unistd.h>  bool run = true;  void sig_handler(int signo) {   if (signo == sigint)   {     printf("received sigint\n");     run = false;   } }  int main(void) {   if (signal(sigint, sig_handler) == sig_err)   printf("\ncan't catch sigint\n");   // long long wait can issue signal process   while(run)      sleep(1);   return 0; }

instead of printf use return or exit
