## Examples

```csharp
using System.Collections.Generic;
using Unity.Profiling.LowLevel;
using Unity.Profiling.LowLevel.Unsafe;

public class Example
{
    public static unsafe void WriteAllNonDevelopmentStatsToFile(string filePath)
    {
        using (var writer = new System.IO.StreamWriter(filePath))
        {
            var availableStatHandles = new List<ProfilerRecorderHandle>();
            ProfilerRecorderHandle.GetAvailable(availableStatHandles);
            foreach (var h in availableStatHandles)
            {
                var statDesc = ProfilerRecorderHandle.GetDescription(h);
                if (!statDesc.Flags.HasFlag(MarkerFlags.AvailabilityNonDevelopment))
                    continue;

                var name = System.Text.Encoding.UTF8.GetString(statDesc.NameUtf8, statDesc.NameUtf8Len);
                writer.WriteLine($"{name};{statDesc.Flags}");
            }
