Timeouting Program

[kvarnerexpress 0]

Is there an easy way to make my 9 lines of code timeout in 5 minutes(that is no barcode has been entered for 5 mins) and if it timesout have it kill my program?


Code:

cout << "Enter barcode:\r\n";cin.get(ch);while (int(ch) != 13){       cout << ch;       cin.get(ch);       line = line+ch;}myFunction( line );

How does it work?

Technically, no since std::cin halts the program until some key response occurs.
You'd have to test for keystrokes using your own code, which can take some time.

But anyway, here's you five minute time out code.

#include <iostream>#include <ctime.h>int main(){  clock_t  x;  x = clock () + 300 * CLK_TCK;  //300 seconds = 5 minutes  while (x > clock())          //basically test for 5 minutes in clock ticks    {     //place keytest code here...    }return 0;}
