Too much to list all, but includes (in no particular order): - Cleanup for 64-bit builds, MSVC warnings. - Structured help - Help file compiler. - Supports volsets, writes/create work. - Support for I18n in messages, help. - Makefiles. - Initialize volume/volset - Command line editing/history Builds and works on Linux and Windows (VS). Not recently built or tested on other platforms, but not intentinonally broken.

/* To set up physical I/O for a new system a group of phyio
|
|
* routines need to be set up. They are:-
|
|
* phyio_show() which doesn't need to do anything - but
|
|
* it would generally print some statistics
|
|
* about the other phyio calls.
|
|
* phyio_path() returns the full path of the supplied filnam.a The
|
|
* returned character string must be deallocated by the
|
|
* caller.
|
|
* phyio_init() to prepare a device for use by future
|
|
* read/write calls. The device name would usually
|
|
* map to a local device - for example rra: to /dev/rra
|
|
* on a Unix system. The call needs to return a handle
|
|
* (channel, file handle, reference number...) for
|
|
* future reference, and optionally some device
|
|
* information.
|
|
* phyio_done() makes a device unavailable.
|
|
* phyio_read() will return a specified number of bytes into a
|
|
* buffer from the start of a 512 byte block on the
|
|
* device referred to by the handle.
|
|
* phyio_write() will write a number of bytes out to a 512 byte block
|
|
* address on a device.
