Routine Description:
This routine is the main program for AutoConv
Arguments:
argc, argv - Supplies the fully qualified NT path name of the
the drive to check. The syntax of the autoconv
command line is:
AUTOCONV drive-name /FS:target-file-system [/v] [/s] [/o] [/cvtarea:filename]
/v -- verbose output
/s -- run from setup
/o -- pause before the final reboot (oem setup)
/cvtarea:filename
-- convert zone file name
/nochkdsk
-- skips chkdsk and go straight to conversion
Return Value:
0 - Success.
1 - Failure.
