## NAME

add\_timer - start a timer

## SYNOPSIS

**void add\_timer(struct timer\_list \*** *timer***);**

## DESCRIPTION

The kernel will do a -\>function(-\>data) callback from the timer interrupt at the -\>expires point in the future. The current time is 'jiffies'.

The timer's -\>expires, -\>function (and if the handler uses it, -\>data) fields must be set prior calling this function.

Timers with an -\>expires field in the past will be executed in the next timer tick.
