device-streams

Amiga tool for copying between block devices and streams/files, similar to UNIX

`dd`.

Originally released by Christian E. Hopps in 1993, updated to be useful today.

Requires AmigaOS 2.04+.

Usage

Run the command with `-h` parameter to display usage information.

Examples

Print RDB device and partition information.

5.Ram Disk:> devstreams/rdbinfo
Device: "scsi.device"  Unit: 0  Capacity: 114473.4 Megs
DiskVendor: FUJITSU  DiskProduct MHV2120AH        DiskRevision: 0000
Cylinders: 232581  Heads: 16  Blks-p-Trk: 63 [Blks-p-Cyl: 1008]
Total Blocks: 234441648  Block Size 512
64bit

--| Partition: "DH0" Capacity: 1023.7 Megs
--| Start Block: 3024  End Block: 2099663 Total Blocks: 2096640
--| Block Size: 512

--| Partition: "DH1" Capacity: 10239.4 Megs
--| Start Block: 2099664  End Block: 23070095 Total Blocks: 20970432
--| Block Size: 512
--| 64bit
###

Dump a partition into a file.

5.Ram Disk:> devstreams/devtostream --output=DH1:dump.dd --rdb-name=DH0
--verbose

write from partition "DH0" to file "DH1:dump.dd"? [Ny]:y
writing: 0x00200950 -> 0x002009cf  [100%]

Improvements

Cleaned up code.
Removed SAS/C-isms and updated to build in modern toolchains.
Use of 64bit offsets throughout.
Safeguards added against 32bit overflow wraparound.
(soon) Trackdisk 64 support.

Building

The new build process uses GNU Make. Simply review the Makefile and run `make`.

Alternatively,

`make clean` will delete all artifacts.
`make lint` will format the code to standards.
`make dist` will prepare a lha archive with the binaries.

Development is done using the `bebbo/amiga-gcc` crossdev toolchain.
