Thread: Setting time length of program

Look up the time() function. It returns the number of seconds since Jan 1,1970 and increments every second...

Code:

unsigned long RunTime;
unsigned long EndTime;

// run for 60 seconds then quit
EndTime = time(null) + 60;

While (EndTime > RunTime)
 { RunTime = Time(null);

    // do a mess of stuf

  }
