Declaration

public static IntPtr CreateMarker(char* name, int nameLen, ushort categoryId, Unity.Profiling.LowLevel.MarkerFlags flags, int metadataCount);

Parameters

name A marker name.
categoryId A profiler category identifier.
flags The marker flags.
metadataCount The metadata parameters count, or 0 if no parameters are expected.
nameLen Marker name string length.

Returns

IntPtr Returns the marker native handle.

Description

Constructs a new Profiler marker handle for code instrumentation.

Use profiler marker handle with ProfilerUnsafeUtility methods only.
The categoryId parameter associates the marker with one of the predefined categories in ProfilerCategory struct.

Note: Markers created with CreateMarker automatically get MarkerFlags.Script flag.

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.Default, 0); static unsafe void DoWork(int num) { ProfilerUnsafeUtility.BeginSample(markerHandle); //... ProfilerUnsafeUtility.EndSample(markerHandle); } }

Use CreateMarker to set metadata parameter names when passing metadata with :ref::BeginSampleWithMetadata method.

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

class Example { static IntPtr MakeMarkerWithIntMetadata(string name, string paramName) { var handle = ProfilerUnsafeUtility.CreateMarker(name, ProfilerUnsafeUtility.CategoryScripts, MarkerFlags.Default, 1); ProfilerUnsafeUtility.SetMarkerMetadata(handle, 0, paramName, (byte)ProfilerMarkerDataType.Int32, (byte)ProfilerMarkerDataUnit.Count); return handle; }

static readonly IntPtr markerHandle = MakeMarkerWithIntMetadata("MyMarker", "Work Idx");

static unsafe void DoWork(int num) { var metadata = stackalloc ProfilerMarkerData[1]; metadata[0].Type = (byte)ProfilerMarkerDataType.Int32; metadata[0].Size = (uint)UnsafeUtility.SizeOf<int>(); metadata[0].Ptr = UnsafeUtility.AddressOf(ref num); ProfilerUnsafeUtility.BeginSampleWithMetadata(markerHandle, 1, metadata); //... ProfilerUnsafeUtility.EndSample(markerHandle); } }
