Undocumented function syssetup.dll.SetupQueryRegisteredOsComponent

It's something like

BOOL SetupQueryRegisteredOsComponent(IN const IID *const pIid, IN OUT 
LPVOID component_data, IN OUT LPVOID exception_data, DWORD reserved1, 
DWORD reserved2);

component_data structure max length is 0xDC, exception_data's is 0x454; 
first argument of both is structure size. I wonder if they defined in 
setupapi.h already.
