 322      * information in the cabinet.  Perhaps that's correct -- that is, perhaps
 323      * this API is supposed to support "streaming" cabinets which are embedded
 324      * in other files, or cabinets which begin at file offsets other than zero.
 325      * Otherwise, I should instead go to the absolute beginning of the file.
 326      * (Either way, the semantics of wine's FDICopy require me to leave the

 328      * ought to duplicate the native behavior in the FDIIsCabinet API, not here.
 329      *
 330      * So, the answer lies in Windows; will native cabinet.dll recognize a
 331      * cabinet "file" embedded in another file?  Note that cabextract.c does
 332      * support this, which implies that Microsoft's might.  I haven't tried it
 333      * yet so I don't know.  ATM, most of wine's FDI cabinet routines (except
 334      * this one) would not work in this way.  To fix it, we could just make the
 335      * various references to absolute file positions in the code relative to an
 336      * initial "beginning" offset.  Because the FDICopy API doesn't take a
 337      * file-handle like this one, we would therein need to search through the
 338      * file for the beginning of the cabinet (as we also do in cabextract.c).
 339      * Note that this limits us to a maximum of one cabinet per. file: the first.
 340      *
 341      * So, in summary: either the code below is wrong, or the rest of fdi.c is
 342      * wrong... I cannot imagine that both are correct ;)  One of these flaws
 343      * should be fixed after determining the behavior on Windows.   We ought
