Parameters
Index of the Profiler sample.

Type | Description |
|---|---|
| int | Returns Profiler marker indentifier. Returns invalidMarkerId for invalid index. |
Remarks
The Profiler uses unique identifier for each marker created during profiling session. Marker can generate many samples which can be retrieved by RawFrameDataView.
All samples generated by the same marker have the same integer marker identifier and the same name.
Marker identifiers are persistent for the entire profiling session.
