ITuningSpace::get_FrequencyMapping

The get_FrequencyMapping method retrieves the frequency mapping previously created by the network provider by a call to put_FrequencyMapping.

Syntax

HRESULT get_FrequencyMapping(
    BSTR* pMapping
    );

Parameters

pMapping

[out] Pointer to a variable that receives the frequency mappings created by the Network Provider filter.

Return Values

Returns S_OK if successful. If the method fails, error information can be retrieved using the standard COM IErrorInfo interface.

Remarks

The returned BSTR is treated as a binary blob. It is expected to contain embedded NULL values, and it may be formatted internally by the BDA Network Provider.

The caller must release the returned BSTR by calling SysFreeString.
