C Function Prototype

ViStatus IviSpecAn_GetMarkerName (ViSession vi, ViInt32 index, ViInt32 nameBufferSize, ViChar[] name);

Purpose

This function returns the specific driver defined trace name that corresponds to the one-based index specified by the Index parameter. If you pass in a value for the Index parameter that is less than one or greater than the value of the IVISPECAN_ATTR_MARKER_COUNT attribute, the function returns an empty string in the Name parameter and returns the Invalid Value error.

Note: For an instrument with only one Marker, i.e. the IVISPECAN_ATTR_MARKER_COUNT attribute is one, the driver may return an empty string.
