Use for the flow continuation point.
An example of a flow start point is job scheduling. For instance, IJobExtensions.Schedule generates an implicit Begin Profiler flow event and IJob.Execute generates an implicit Next event.

public class Example { static readonly ProfilerMarker k_ScheduleTasksMarker = new ProfilerMarker("Schedule Task"); static readonly ProfilerMarker k_TaskMarker = new ProfilerMarker("Task");
static void EmitFlowEventAndChainThread(uint flowId) { // Mark the next k_TaskMarker as a beginning of the flow ProfilerUnsafeUtility.FlowEvent(flowId, ProfilerFlowEventType.Next); using (k_TaskMarker.Auto()) { // Do work } }
static void ScheduleTask() { using (k_ScheduleTasksMarker.Auto()) { var flowId = ProfilerUnsafeUtility.CreateFlow(ProfilerUnsafeUtility.CategoryScripts); // Mark the parent k_ScheduleTasksMarker as a beginning of the flow ProfilerUnsafeUtility.FlowEvent(flowId, ProfilerFlowEventType.Begin); var thread = new Thread(() => EmitFlowEventAndChainThread(flowId)); thread.Start(); } } }
