# AudioDriverPlugInStreamGetPropertyInfo

```
extern OSStatus AudioDriverPlugInStreamGetPropertyInfo(AudioDeviceID inDevice, io_object_t inIOAudioStream, UInt32 inChannel, AudioDevicePropertyID inPropertyID, UInt32 *outSize, Boolean *outWritable);
```

## Parameters

`inDevice`

The AudioDevice whose stream is being queried.

`inIOAudioStream`

The IOAudioStream to query.

`inChannel`

The channel of the property to query where 0 is the main channel.

`inPropertyID`

The AudioDevicePropertyID of the property to query.

`outSize`

A pointer to a UInt32 that receives the size of the property data in bytes
on exit. This can be NULL if the size information is not being requested.

`outWritable`

A pointer to a Boolean that receives indication of whether or not the given
property can be set. This can be NULL if the writability is not being
requested.

## Return Value

An OSStatus indicating success or failure. Note that if the plug-in does not
implement the given property, it should return
