Property ID to fetch.
- dataSize
- Int32
The expected size of the property (must match the underlying assumption for the size).

-
IntPtr
nativeint

GetProperty(AudioFileStreamProperty, Int32)
Low-level routine used to fetch arbitrary property values from the underlying AudioFileStream object.
public IntPtr GetProperty (AudioToolbox.AudioFileStreamProperty property, out int size);member this.GetProperty : AudioToolbox.AudioFileStreamProperty * -> nativeintParameters
- property
- AudioFileStreamProperty
Property ID to fetch.
- size
- Int32
The size in bytes of the property.
Returns
nativeint
If the return value from this method is different that IntPtr.Zero, the value pointed to contains the value of the property.
Remarks
This method will query the underlying AudioFileStream object for the size of the specified property and allocate the memory needed for it using Marshal.AllocHGlobal method.
You are responsible for releasing the memory allocated by this method by calling Marshal.FreeHGlobal.
This updates the LastError property.
