How to block and unblock the ctrl-c singal in my windows application?

Hi,

I am having a use case where I want to block the ctrl-c signal generated by console application for doing some processing and then after the processing is done I would like to continue with the program by handling the ctrl-c signal handler.

I am able to do this successfully on UNIX platfroms by using

sigprocmask(SIG_BLOCK   and

sigprocmask(SIG_UNBLOCK, But i am not able to do the same on windows platform.

For implementing the same on windows i am using below logic:

 signal(SIGINT, signal_handler); // To register the signal with the program
 if( SetConsoleCtrlHandler( NULL, TRUE ) == 1) // this will disable the signal handler
  { 
  Sleep(5000);
  } else {
   printf("failed to disable the signal handler.\n");
  }

if( SetConsoleCtrlHandler( NULL, FALSE ) ){ // this will enable the signal handler after the sleep is over
  Sleep(5000);
}

Here the issue I am facing is if user presses ctrl-c before the  disabling the singal handler, then in that case the ctrl-c signal is getting ignored and I am missing it. So when the program comes back to signal handler by enabling it, then we are missing the signal.

I would like to know if there is any way in windows we can block and unblock the signals.

Any help will be really appreciated.

Thanks,
