lr_end_timer

Stops a timer.

double lr_end_timer (merc_timer_handle_t timer); 

Arguments

lr_end_timer stops a timer that began timing when lr_start_timer was called. It returns the elapsed time. The resolution depends on the runtime environment. The maximum resolution is a microsecond.

Return Values

The function returns the elapsed time in seconds. In Java, the function returns the elapsed time in milliseconds.

Parameterization

You cannot use standard parameterization for any arguments in this function.

Example

In the following segment, lr_start_timer and lr_end_timer calculate the time spent on the call to web_reg_save_param. This is then subtracted from the time spent on transaction "Web-tours" with lr_wasted_time.

double time_elapsed;
merc_timer_handle_t timer;
lr_start_transaction ("Web-tours");
web_url("home;sz=234x60;tile=1;ord=977672495775323400",
    "URL=http://ad.doubleclick.net/...ord=977672495775323400",
     ..
    "Mode=URL",
    LAST );
timer = lr_start_timer();
web_reg_save_param("WCSParam_Diff1", "LB=http://", "RB=/", "Ord=17", "Search=body", LAST );

/* result is in seconds */
time_elapsed = lr_end_timer(timer);
lr_output_message("Duration of web_reg_save_param = %lf", time_elapsed);

/* Subtract time spent on call web_reg_save_param from all open transactions. 
Wasted time is measured in milliseconds */ 
lr_wasted_time(1000 * time_elapsed);
