int32 __stdcall niWLANG_RFSGRetrieveRFBlankingMarkerPositions (ViSession rfsgSession, char waveformName[], int32 rfBlankingMarkerPositionsArraySize, int32 rfBlankingMarkerPositions[], int32 *actualRFBlankingMarkerPositionsArraySize);


Returns the RF blanking marker positions stored in the RFSG database. The function uses the waveform name as the key to retrieve the waveform properties.
