RemoveRegistry - Supplies TRUE if registry entry is to be removed
SetupMode - Supplies TRUE if invoked through setup
Extend - Supplies TRUE if extending the volume (obsolete)
LogfileSize - Supplies the size of the logfile
Algorithm - Supplies the algorithm to use
ArgCount - Supplies the number of arguments given to autochk.
ArgArray - Supplies the arguments given to autochk.
SkipList - Supplies the list of drives to skip checking
Msg - Supplies the outlet of messages
ExitStatus - Retrieves the exit status of chkdsk
Return Value:
