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