ITuningSpace::get_FrequencyMapping method (tuner.h)
[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]
The get_FrequencyMapping method retrieves the frequency mapping previously created by the network provider by a call to put_FrequencyMapping.
Syntax
HRESULT get_FrequencyMapping(
[out] BSTR *pMapping
);
Parameters
[out] pMapping
Pointer to a variable that receives the frequency mappings created by the Network Provider filter.
Return value
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.
