# makeCounterSampleBuffer(descriptor:)

Creates a counter sample buffer.

```
func makeCounterSampleBuffer(descriptor: MTLCounterSampleBufferDescriptor) throws -> any MTLCounterSampleBuffer
```

## Parameters

`descriptor`

An [`MTLCounterSampleBufferDescriptor`](/documentation/Metal/MTLCounterSampleBufferDescriptor) instance.

## Return Value

A new [`MTLCounterSampleBuffer`](/documentation/Metal/MTLCounterSampleBuffer) instance if the method completes successfully;
otherwise Swift throws an error and Objective-C returns `nil`.

## Discussion

The method may produce an error if the GPU driver has exhausted its underlying resources for counter sample buffers.
