IPrintTicketProvider::QueryDeviceNamespace method (prdrvcom.h)
The IPrintTicketProvider::QueryDeviceNamespace method queries the device for its default namespace uniform resource identifier (URI).
Syntax
HRESULT QueryDeviceNamespace(
[out] OUT BSTR *pDefaultNamespace
);
Parameters
[out] pDefaultNamespace
A pointer to a BSTR that receives the namespace URI. The driver places the namespace URI in the buffer that is pointed to by pDefaultNamespace.
IPrintTicketProvider::QueryDeviceNamespace is responsible for allocating the string by means of a call to SysAllocString (described in the Microsoft Windows SDK documentation), but the caller is responsible for freeing the string.
Return value
IPrintTicketProvider::QueryDeviceNamespace should return S_OK if the operation succeeds and E_FAIL otherwise.
