Microsoft DirectX 8.1 (C++)

IScanningTuner::AutoProgram

The AutoProgram method scans for all channels with valid programming.

Syntax

HRESULT AutoProgram();

Parameters

This method takes no parameters.

Return Values

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

Remarks

This method returns immediately, and the scan continues in the background. If the device allows it, the scan can be canceled by calling any other tuning operation. Otherwise, the scan will complete once all channels have been visited once. Internal devices will likely have a software implementation of this feature, and will collect fine-tuning information resulting from the scan. External devices will likely implement this feature, so this is just a means to trigger the process.
