Example: lr_end_timer
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);
