1 /* 2 * 16 Feb 93 Julian Elischer (julian@dialix.oz.au) 3 * 4 * $FreeBSD$ 5 */ 6 7 /* 8 <1> Fixed a conflict with ioctl usage. There were two different 9 functions using code #25. Made file formatting consistent. 10 Added two new ioctl codes: door closing and audio pitch playback. 11 Added a STEREO union called STEREO. 12 5-Mar-95 Frank Durda IV bsdmail@nemesis.lonestar.org 13 14 <2> Added a new ioctl that allows you to find out what capabilities 15 a drive has and what commands it will accept. This allows a 16 user application to only offer controls (buttons, sliders, etc) 17 for functions that drive can actually do. Things it can't do 18 can disappear or be greyed-out (like some other system). 19 If the driver doesn't respond to this call, well, handle it the 20 way you used to do it. 21 2-Apr-95 Frank Durda IV bsdmail@nemesis.lonestar.org 22 */ 23 24 /* Shared between kernel & process */ 25 26 #ifndef _SYS_CDIO_H_ 27 #define _SYS_CDIO_H_ 28 29 #ifndef _KERNEL 30 #include <sys/types.h> 31 #endif 32 #include <sys/ioccom.h> 33 34 union msf_lba { 35 struct { 36 unsigned char unused;
