LIBDSK page

LIBDSK is a library for accessing discs and disc image files. It is intended for use in:

Emulator tools - converting between real floppy discs and disc images, as CPCTRANS / PCWTRANS do under DOS.
Filesystem utilities - CPMTOOLS is configurable to use LIBDSK, thus allowing the use of CPMTOOLS on emulator .DSK images. To do this, install LIBDSK and then build CPMTOOLS, using "./configure --with-libdsk". For CPMTOOLS 1.9 or 2.0, you will also need to apply this patch.
Emulators - it is possible to use LIBDSK as part of an emulator's floppy controller emulation, thus giving the emulator transparent access to .DSK files or real discs.

New in v1.1.1

Support has been added for the APRIDISK file format.
LibDsk can be programmed to retry automatically in case of error.
Supports double-stepping, so 360k discs can be read in 1.2Mb drives.

New in v1.1.0

The example utilities take parameters in any order.
Support has been added for the 400k disc images used by the NanoWasp emulator.
The 32-bit Windows library can use the 16-bit library for floppy disc access. This allows 32-bit LibDsk programs to read ADFS floppies, for example.

New in v1.0.0

Minor portability fixes.

New in v0.9.9

More bug fixes.
Now compiles under 16-bit DOS and Windows.
Projects included for Visual C++, Borland C++, Pacific C and DJGPP.

New in v0.9.5

Bug fixes in the POSIX and MYZ80 drivers.

New in v0.9.1

Squeeze code rewritten from scratch to avoid possible licence conflict.

New in v0.9.0

Support for compressed disc image files (.SQ and .gz).
Support for reading/writing deleted data.
Major bug fixes in the support for extended CPCEMU-format disc images.
BBC Micro DFS added to the list of built-in formats.

Disc types supported

LIBDSK has drivers for:

Raw files (including /dev/fdn).
.DSK files, as used in CPCEMU, JOYCE and other Sinclair/Amstrad emulators.
MYZ80 hard drive image files.
NanoWasp floppy image files.
.CFI (Compressed Floppy Image) files, as created by FDCOPY.COM under DOS.
The Linux floppy drive (supports CPC System and Data formats, which the standard "Raw file" driver does not).
The Windows 3.x/95/98/ME/NT/2000 floppy drive.
The DOS floppy drive (via the PC BIOS).

LIB765

Lib765 is the floppy controller emulation from JOYCE, separately packaged. It is (in some sense) the reverse of LibDsk; it converts uPD765a commands into LibDsk API calls. It should come in handy if you're writing a PCW, CPC or Spectrum+3 emulator; if you want to use it in a PC emulator, you'll need to add features such as DMA.

New in v0.3.1

(v0.3.1) Fixed default error handler.
(v0.3.0) Should be compatible with MacOS X.
