* Compact Disc Control Utility by Serge V. Vakulenko <vak@cronyx.ru>.
|
|
* Based on the non-X based CD player by Jean-Marc Zucconi and
|
|
* Andrey A. Chernov.
|
|
*
|
|
* Fixed and further modified on 5-Sep-1995 by Jukka Ukkonen <jau@funet.fi>.
|
|
*
|
|
* 11-Sep-1995: Jukka A. Ukkonen <jau@funet.fi>
|
|
* A couple of further fixes to my own earlier "fixes".
|
|
*
|
|
* 18-Sep-1995: Jukka A. Ukkonen <jau@funet.fi>
|
|
* Added an ability to specify addresses relative to the
|
|
* beginning of a track. This is in fact a variation of
|
|
* doing the simple play_msf() call.
|
|
*
|
|
* 11-Oct-1995: Serge V.Vakulenko <vak@cronyx.ru>
|
|
* New eject algorithm.
|
|
* Some code style reformatting.
|
|
*
|
|
* 13-Dec-1999: Knut A. Syed <kas@kas.no>
|
|
* Volume-command modified. If used with only one
|
|
* parameter it now sets both channels. If used without
|
|
* parameters it will print volume-info.
|
|
* Version 2.0.1
|
|
*
|
|
* 27-Jun-2008 Pietro Cerutti <gahr@FreeBSD.org>
|
|
* Further enhancement to volume. Values not in range 0-255
|
|
* are now reduced to be in range. This prevents overflow in
|
|
* the uchar storing the volume (256 -> 0, -20 -> 236, ...).
|
|
* Version 2.0.2
|
|
*
