Routine Description:
|
|
|
|
This routine copies on floppy diskette to another floppy diskette.
|
|
|
|
Arguments:
|
|
|
|
SrcNtDriveName - Supplies the NT style drive name for the source.
|
|
DstNtDriveName - Supplies the NT style drive name for the destination.
|
|
SrcDosDriveName - Supplies the DOS style drive name for the source.
|
|
DstDosDriveName - Supplies the DOS style drive name for the destination.
|
|
Message - Supplies an outlet for messages.
|
|
|
|
Return Value:
|
|
|
|
0 - The disks are the same.
|
|
1 - The disks are different.
|
|
3 - A hard error occurred.
|
|
4 - An initialization error occurred.
