3.20.9.3 IWindowsDriverUpdate::DriverManufacturer (Opnum 55)

  • Article

The IWindowsDriverUpdate::DriverManufacturer (opnum 55) method retrieves the language-invariant name of the driver manufacturer.

 HRESULT DriverManufacturer(
   [out, retval] BSTR* retval
 );

retval: A string containing the language-invariant name of the driver manufacturer. If the driver manufacturer name is not available, then this MUST be NULL.

Return Values: The method MUST return information in an HRESULT data structure. The severity bit in the structure identifies the following conditions:

  • If the severity bit is set to 0, the method completed successfully.

  • If the severity bit is set to 1, the method failed and encountered a fatal error.

Exceptions Thrown: No exceptions are thrown beyond those thrown by the underlying RPC protocol [MS-RPCE].

This method SHOULD return the string returned by a call to the DriverManufacturer method on the IWindowsDriverUpdateEntry instance referred to by the DefaultWindowsDriverUpdateEntry ADM element.
