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