  [in, optional] HMACHINE hMachine
);

Pointer to a string that identifies the device interface instance of the registry subkey to delete.

Return value

If the operation succeeds, the function returns CR_SUCCESS. Otherwise, it returns one of the CR_-prefixed error codes defined in Cfgmgr32.h.

Remarks

Note

The cfgmgr32.h header defines CM_Delete_Device_Interface_Key_Ex as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
