## Declaration

```occ
size_t GetAvailableSampleRates(double *out_sample_rates, size_t in_num_rates);
```

## Parameters

- `out_sample_rates`: A pointer to a buffer of type double whose size corresponds to in_num_rates. After the call completes, this buffer contains the available sample rates.
- `in_num_rates`: The number of rates in the out_sample_rates buffer.

## Return Value

Return Value A size_t that indicates how many rates were set in the out_sample_rates buffer.

## Discussion

Discussion This method synchronizes by using the work queue created by the object.
