# getCommand

## Declaration

```occ
virtual IOCommand *getCommand(
 bool blockForCommand = true); 
```

## Parameters

- `blockForCommand`: If the caller would like to have its thread slept until a command is available, it should pass true, else false.

## Return Value

Return Value If the caller passes true in blockForCommand, getCommand guarantees that the result will be a pointer to an IOCommand object from the pool. If the caller passes false, s/he is responsible for checking whether a non-NULL pointer was returned.

## Overview

Overview The getCommand method is used to get a pointer to an object of type IOCommand from the pool.
