IPrintSchemaCapabilities::GetFeature method (printerextension.h)
Gets a named feature from the PrintCapabilities, by name and full namespace URI.
Syntax
HRESULT GetFeature(
[in] BSTR bstrName,
[in] BSTR bstrNamespaceUri,
[out, retval] IPrintSchemaFeature **ppFeature
);
Parameters
[in] bstrName
The base value of the "name" attribute of the Feature element. For example, for the Print Schema feature, the tag looks like this <psf:Feature name="psk:JobOutputBin">, showing a base value of "JobOutputBin".
[in] bstrNamespaceUri
The namespace URI value of the "name" attribute of the Feature element. For example, for the Print Schema feature, the tag looks like this <psf:Feature name="psk:JobOutputBin">, with a base name value of "JobOutputBin", and the namespace URI of the public Print Schema is "https://schemas.microsoft.com/windows/2003/08/printing/printschemakeywords". If the feature is not defined in the public Print Schema, then this should be the URI of the private namespace that defines the feature.
[out, retval] ppFeature
The returned feature.
Return value
This method returns an HRESULT value.
Remarks
When the requested feature, option or property is not found, this method returns S_FALSE and sets a NULL pointer on the output object of the feature, option or property.
So if the IPrintSchemaTicket object does not contain the specified feature, option or property, the app must obtain an IPrintSchemaCapabilities object and query it via IPrintSchemaCapabilities::GetFeatureByKeyName or via IPrintSchemaCapabilities::GetFeature.
