# AudioDeviceDestroyIOProcID(_:_:)

## Declaration

```swift
func AudioDeviceDestroyIOProcID(_ inDevice: AudioObjectID, _ inIOProcID: AudioDeviceIOProcID) -> OSStatus
```

## Parameters

- `inDevice`: The AudioDevice from which the ID came.
- `inIOProcID`: The AudioDeviceIOProcID to get rid of.

## Return Value

Return Value An OSStatus indicating success or failure.

## Discussion

Discussion Destroys an AudioDeviceIOProcID. AudioDeviceIOProcIDs allow for the client to register the same function pointer with a device multiple times
