Purpose

Changes the alarm relative to the old value

Protoype

void CTimerMngr::ChangeAlarm (string str_timer, int i_change)

Parameters

Description

This function changes the alarm by a given number of milliseconds relative from it's current set alarm. So if you want to reduce or increase a timer's alarm, you can use this function rather than polling for the current alarm and changing it with SetAlarm().

NOTE: The function will not let you reduce an alarm into the negative numbers. It will bottom out at 0.

Use

CTimerMngr timer;

// reduce the timer by 1 second
timer.ChangeAlarm("my_alarm", -1000);

// increase the alarm by 5 seconds
timer.ChangeAlarm("my_alarm", 5000);
