IScanningTunerEx::ResumeCurrentScan

This topic applies to Windows Vista.

The ResumeCurrentScan method resumes scanning the range of frequencies specified in PerformExhaustiveScan.

Syntax

  HRESULT ResumeCurrentScan(
    HEVENT 
  hEvent

  );

Parameters

hEvent

[in]  Handle to an event created by the application. When the tuner locks onto a signal, it signals this event.

Return Values

When the method succeeds, it returns S_OK. Otherwise it returns an HRESULT error code.

Remarks

When the application calls PerformExhaustiveScan, the tuner scans until it locks onto a signal. Then it sets the application's event handle. To resume scanning for the next valid signal in original range of frequencies, the application can call ResumeCurrentScan.

Requirements

Header: Include Tuner.h.
