SPDRP_CAPABILITIES
The function retrieves a bitwise OR of the followingCM_DEVCAP_Xxx flags in a DWORD. The device capabilitiesthat are represented by these flags correspond to the devicecapabilities that are represented by the members of theDEVICE_CAPABILITIESstructure. The CM_DEVCAP_Xxx constants are defined incfgmgr32.h.

- SPDRP_SERVICE
- The function retrieves a REG_SZ string containing the servicename for a device.
- SPDRP_UI_NUMBER
- The function retrieves a DWORD value set to the value of theUINumber member of the device'sDEVICE_CAPABILITIES structure.
- SPDRP_UI_NUMBER_DESC_FORMAT
- The function retrieves a format string (REG_SZ) used to displaythe UINumber value.
- SPDRP_UPPERFILTERS
- The function retrieves a REG_MULTI_SZ string that contains thenames of a device's upper filter drivers.

Return Value
SetupDiGetDeviceRegistryProperty returns TRUEif the call was successful. Otherwise, it returns FALSE and thelogged error can be retrieved with a call toGetLastError.SetupDiGetDeviceRegistryProperty returns theERROR_INVALID_DATA error code if the requested property does notexist for a device or if the property data is not valid.
