# AvailabilityNonDevelopment

> Specifies that marker is present in non-development Players.

## Definition

* **Type:** Field
* **Namespace:** [Unity.Profiling.LowLevel](/engine/6000.3/script-reference/unity/profiling/lowlevel.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
AvailabilityNonDevelopment = 8
```

### Remarks

Use *AvailabilityNonDevelopment* to determine whether or not a profiler marker or counter is available in non-development Players.

```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}");
            }
        }
    }
}
```

Use *AvailabilityNonDevelopment* to signify that a profiler marker created with the help of [ProfilerUnsafeUtility.CreateMarker](/engine/6000.3/script-reference/unity/profiling/lowlevel/unsafe/profilerunsafeutility/createmarker.md) is available in non-development Players.

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

class Example
{
    static readonly IntPtr markerHandle = ProfilerUnsafeUtility.CreateMarker("MyMarker", ProfilerUnsafeUtility.CategoryScripts, MarkerFlags.AvailabilityNonDevelopment, 0);
    static unsafe void DoWork(int num)
    {
        ProfilerUnsafeUtility.BeginSample(markerHandle);
        //...
        ProfilerUnsafeUtility.EndSample(markerHandle);
    }
}
```

**Note:**

*AvailabilityNonDevelopment* flag has no effect on the [ProfilerMarker](/engine/6000.3/script-reference/unity/profiling/profilermarker.md) creation as [ProfilerMarker](/engine/6000.3/script-reference/unity/profiling/profilermarker.md) API is Development Player only.
