# setTimeoutFunc

Set's timeout as the function of calloutEntry.

## Declaration

```occ
virtual void setTimeoutFunc(); 
```

## Overview

Overview IOTimerEventSource is based upon the kern/thread_call.h APIs currently. This function allocates the calloutEntry member variable by using thread_call_allocate(timeout, this). If you need to write your own subclass of IOTimerEventSource you probably should override this method to allocate an entry that points to your own timeout routine.
