@ -498,6 +498,14 @@ Provides several routines that deal with disk drive I/O, such as:
- delete and rename files on the disk
- send arbitrary CbmDos command to disk drive
For simplicity sake, this library is designed to work on a *single* open file
for reading, and a *single* open file for writing at any time only.
If you need to load or save to more than one file at a time, you'll have
to write your own I/O routines (or supplement the ones found here)
You can set the active *disk drive number*, so it supports multiple drives, just one at a time.
It does not support reading from more than one file or writing to more than one file at a time.
Commander X16 additions:
Headerless load and save routines are available (load_raw, save_raw).
On the Commander X16 it tries to use that machine's fast Kernal loading routines if possible.

.. note::
For simplicity sake, this library is designed to work on a *single* open file
for reading, and a *single* open file for writing at any time only.
If you need to load or save to more than one file at a time, you'll have
to write your own I/O routines (or supplement the ones found here)
Opening a file using f_read() or f_read_w() doesn't set the default i/o channels to that file.
In fact, after calling routines in diskio, it resets the input and output channels to their
defaults (keyboard and screen).
If you are going to do kernal I/O calls like CHRIN/CHROUT/(M)ACPTR yourself on the files opened via diskio,
you must use reset_read_channel() or reset_write_channel() before doing so. This makes
the correct file channel active. The diskio routines themselves do this as well internally.
.. note::
If you are using the X16 emulator with HostFS, and are experiencing weird behavior with these
routines, please first try again with an SD-card image instead of HostFs.
It is possible that there are still small differences between HostFS and actual CBM DOS in the X16 emulator.
.. note::
You can set the active disk drive number, so it supports multiple drives, just one at a time.
It does not support reading from more than one file or writing to more than one file at a time.
.. attention::
Error handling is peculiar on CBM dos systems (C64, C128, cx16, PET). Read the
descriptions for the various methods in this library for details and tips.
