Op�ration sur les LARGE

Apparement ton LARGE_INT serait une structure pour coder un nombre sur 64bit. J'ai trouv� ce code :

  LARGE_INTEGER ticksPerSecond;
  LARGE_INTEGER tick;   // A point in time
  LARGE_INTEGER time;   // For converting tick into real time
 
  // get the high resolution counter's accuracy
  QueryPerformanceFrequency(&ticksPerSecond);
 
  // what time is it?
  QueryPerformanceCounter(&tick);
 
  // convert the tick number into the number of seconds
  // since the system was started...
  time.QuadPart = tick.QuadPart/ticksPerSecond.QuadPart;
 
  //get the number of hours
  int hours = time.QuadPart/3600;
 
  //get the number of minutes
  time.QuadPart = time.QuadPart - (hours * 3600);
  int minutes = time.QuadPart/60;
 
  //get the number of seconds
  int seconds = time.QuadPart - (minutes * 60);
 
  AnsiString result = "The system was started ";
  result += IntToStr(hours) + " hours ";
  result += IntToStr(minutes) + " minutes ";
  result += IntToStr(seconds) + " and ";
  result += AnsiString(tick.QuadPart % ticksPerSecond.QuadPart);
  result += AnsiString("/") + ticksPerSecond.QuadPart;
  result += " seconds ago.";
 
  printf("%s", result.c_str());

Il fonctionne bien chez moi et apparement, il fait des op�rations sur des types LARGE_INT et utilise ta fonction QueryPerformanceCounter. N'oublie pas d'inclue la biblioth�que stdio.h.
