(This isn't an NT question specifically, but
there doesn't seem to be a "Windows General")

I would like a specification of the format
in which data is stored in the clipboard
when it represents Rich Text.

I think you need to delve into the Windows SDK to learn the format.

See the ms site for developers, it may be something that you can simply download.

I hope this helps !

Hmm, it's a good general tip and might have been useful
in general, but it doesn't really seem worth 200 points.

Anyway, I figured it out, I think.  The clipboard
format seems to be the same as the Rich Text format
itself.  I guess that's logical but for some reason
it didn't occur to me.

See the documentation for clipboard format functions for more information on the possible formats.  EnumClipboardFormats is of particular interest:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceui40/htm/cerefEnumClipboardFormats.asp

When you read data from the clipboard it can be read in a variety of different formats.  All of the different formats are stored separately so there isn't one place where all of the data is stored.  It is up to the application that writes to the clipboard to store as many different formats as relevant when the user hits the copy button.  Basically, the structure of the data is up to the application as well (with the exception of bmp's, riff files, wav files, etc.).  Here is an example of the output from EnumClipboardFormats and GetClipboardData for a simple rtf snippet:

D:\Source>EnumClipboardFormats
format(49161): DataObject
format(49166): Object Descriptor
format(49272): Rich Text Format
format(49457): HTML Format
format(1): <no name>
format(13): <no name>
format(3): <no name>
format(49163): Embed Source
format(49156): Native
format(49155): OwnerLink
format(49165): Link Source
format(49167): Link Source Descriptor

format(16): <no name>
