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.

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.
- Use dos.library for file I/O.
- Trackdisk 64 support.
- NSD support.
Binaries built
- rdbinfo: Examines RDB partition tables and lists the partitions.
- streamtodev: Writes data from a stream into a device.
- devtostream: Reads data from a device into a stream.
- xstreamtodev: As streamtodev but with extra options to specify block range.
- xdevtostream: As devtostream but with extra options to specify block range.
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.
https://github.com/bebbo/amiga-gcc
With some care so that building with vbcc
is also supported.
