S_OK	The method succeeded.

Remarks

You might want to design several different type of tables of contents. In that case, you can distinguish between types by creating a GUID that represents each type. You can identify a table of contents as a particular type by setting the guidType member of a TOC_DESCRIPTOR structure and then passing the TOC_DESCRIPTOR structure to IToc::SetDescriptor.
