LR脚本信息函数-lr_start_timer和lr_end_timer

为了计算时间更加精确，可以用这个函数去掉LR自身的检查点所浪费的时间。如text check and image time

Action()
{
 double time_elapsed, duration, waste;
 merc_timer_handle_t timer;
 int m,n;
  lr_start_transaction("test");

 timer=lr_start_timer();
//   不想记录到transaction时间的操作

 for (m=;m<;m++)
 lr_output_message ("%d",m);
 time_elapsed = lr_end_timer(timer);
 waste = time_elapsed * ;
 lr_wasted_time(waste);
 lr_end_transaction("test", LR_AUTO);
 return ;
}

Action()
{
double time_elapsed;
merc_timer_handle_t timer;

        time_elapsed = lr_end_timer(timer);

// Convert to millisecond.s

        waste = time_elapsed * ;

        the transaction. */
