# AudioObjectGetPropertyData(_:_:_:_:_:_:)

## Declaration

```swift
func AudioObjectGetPropertyData(_ inObjectID: AudioObjectID, _ inAddress: UnsafePointer<AudioObjectPropertyAddress>, _ inQualifierDataSize: UInt32, _ inQualifierData: UnsafeRawPointer?, _ ioDataSize: UnsafeMutablePointer<UInt32>, _ outData: UnsafeMutableRawPointer) -> OSStatus
```

## Parameters

- `inObjectID`: The AudioObject to query.
- `inAddress`: An AudioObjectPropertyAddress indicating which property is being queried.
- `inQualifierDataSize`: A UInt32 indicating the size of the buffer pointed to by inQualifierData. Note that not all properties require qualification, in which case this value will be 0.
- `inQualifierData`: A buffer of data to be used in determining the data of the property being queried. Note that not all properties require qualification, in which case this value will be NULL.
- `ioDataSize`: A UInt32 which on entry indicates the size of the buffer pointed to by outData and on exit indicates how much of the buffer was used.
- `outData`: The buffer into which the AudioObject will put the data for the given property.

## Return Value

Return Value An OSStatus indicating success or failure.

## Discussion

Discussion Queries an AudioObject to get the data of the given property and places it in the provided buffer.
