# MusicEventIteratorGetEventInfo(_:_:_:_:_:)

Gets information about the event at a music event iterator’s current position.

## Declaration

```swift
func MusicEventIteratorGetEventInfo(_ inIterator: MusicEventIterator, _ outTimeStamp: UnsafeMutablePointer<MusicTimeStamp>, _ outEventType: UnsafeMutablePointer<MusicEventType>, _ outEventData: UnsafeMutablePointer<UnsafeRawPointer?>, _ outEventDataSize: UnsafeMutablePointer<UInt32>) -> OSStatus
```

## Parameters

- `inIterator`: The music event iterator whose current event you want information about.
- `outTimeStamp`: On output, the timestamp of the music event, in beats.
- `outEventType`: On output, the type of music event. For possible event types, see doc://com.apple.audiotoolbox/documentation/AudioToolbox/MusicEventType.
- `outEventData`: On output, a reference to the music event data. The type of data is specified by the outEventType parameter. Do not modify the referenced data directly; to change an event, use the doc://com.apple.audiotoolbox/documentation/AudioToolbox/MusicEventIteratorSetEventInfo(_:_:_:) function.
- `outEventDataSize`: On output, the size, in bytes, of the music event data in the outEventData parameter.

## Return Value

Return Value A result code.

## Discussion

Discussion Pass NULL for any output parameter whose information you do not need.
