    Array of DIDEVICEOBJECTDATA structures to receive the buffered data.

	If this parameter is NULL, the buffered data is not stored anywhere, but all other side effects take place. 
pdwInOut
    On entry, the number of elements in the array pointed to by the rgdod parameter.

dwFlags
    Flags that control the manner in which data is obtained. 
	This value can be 0 or the following flag.

    DIGDD_PEEK
