Declaration

public int GetSampleMarkerId(int sampleIndex);

Parameters

sampleIndex Index of the Profiler sample.

Returns

int Returns Profiler marker indentifier. Returns invalidMarkerId for invalid index.

Description

Gets Profiler marker indentifier which uniquely identifies sample name.

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.
