[V] SAFEARRAY*. How long is this? How is it to be interpreted?

[P] Length prefixed bytes.

[P] Blob contains an object.

[V][T][P][S] True=-1, False=0.

[V][T][P][S] OLE Automation string.

[V] void* for local use. How long is this? How is it to be interpreted?

[P] Clipboard format.

[P] A Class ID.

It consists of a 32 bit unsigned integer indicating the size of the structure, a 32 bit signed integer indicating (Clipboard Format Tag) indicating the type of data that it contains, and then a byte array containing the data.

The valid Clipboard Format Tags are:

• Thumbnail#CFTAG_WINDOWS
• Thumbnail#CFTAG_MACINTOSH
• Thumbnail#CFTAG_NODATA
• Thumbnail#CFTAG_FMTID

typedef struct tagCLIPDATA {
// cbSize is the size of the buffer pointed to
// by pClipData, plus sizeof(ulClipFmt)
ULONG              cbSize;
long               ulClipFmt;
BYTE*              pClipData;
} CLIPDATA;
