* The following members of the dest struct control the operation

* of Extract:
|

* filelist [I] A linked list of filenames. Extract only extracts

* directory [I] The destination directory.
|

* lastfile [O] The last file extracted.
|

*
|
||||
* Operation
|
||||
* If flags contains EXTRACT_FILLFILELIST, then filelist will be
|

* filled with all the files in the cabinet. If flags contains

* EXTRACT_EXTRACTFILES, then only the files in the filelist will
|

* be extracted from the cabinet. EXTRACT_FILLFILELIST can be called
