Question

This is the gist the program :

while(true)
{
//bunch of codes that gets data from port ,
//if there is no data it waits here .

}

i am using linux , is there any inbuilt support for keypresses like Ctrl+C . I can catch that using signal(SIGINT, signal_callback_handler); but Ctrl+C has some problem as it gives errors .

i want to get out of this loop on keypress , is this possible ?
If yes , how to do it .

You can signal an interupt

      #include <csignal>

      raise(SIGINT);

or

     raise(SIGABRT);
