Stops the energy detector.

DWORD adiStopEnergyDetector ( CTAHD ctahd )

ctahd CTA context handle returned by ctaCreateContext.

• SUCCESS
• CTAERR_FUNCTION_NOT_ACTIVE
• CTAERR_INVALID_CTAHD
• CTAERR_INVALID_SEQUENCE
• CTAERR_INVALID_STATE

• ADIEVN_ENERGY_DETECT_DONE
  Once the detector has stopped, the ADI service generates a DONE event with the value field set to CTA_REASON_STOPPED.

This function stops the low-level energy detector started by adiStartEnergyDetector. After this function is called, energy and silence transitions are not reported. The energy detector cannot be restarted until the DONE event is received.
