# CFRunLoopTimerGetContext(_:_:)

Returns the context information for a CFRunLoopTimer object.

## Declaration

```swift
func CFRunLoopTimerGetContext(_ timer: CFRunLoopTimer!, _ context: UnsafeMutablePointer<CFRunLoopTimerContext>!)
```

## Parameters

- `timer`: The run loop timer to examine.
- `context`: A pointer to the structure into which the context information for timer is to be copied. The information being returned is the same information passed to doc://com.apple.corefoundation/documentation/CoreFoundation/CFRunLoopTimerCreate(_:_:_:_:_:_:_:) when creating timer.

## Discussion

Discussion The context version number for run loop timers is currently 0. Before calling this function, you need to initialize the version member of context to 0.
