1 /* 2 * Compact Disc Control Utility by Serge V. Vakulenko <vak@cronyx.ru>. 3 * Based on the non-X based CD player by Jean-Marc Zucconi and 4 * Andrey A. Chernov. 5 * 6 * Fixed and further modified on 5-Sep-1995 by Jukka Ukkonen <jau@funet.fi>. 7 * 8 * 11-Sep-1995: Jukka A. Ukkonen <jau@funet.fi> 9 * A couple of further fixes to my own earlier "fixes". 10 * 11 * 18-Sep-1995: Jukka A. Ukkonen <jau@funet.fi> 12 * Added an ability to specify addresses relative to the 13 * beginning of a track. This is in fact a variation of 14 * doing the simple play_msf() call. 15 * 16 * 11-Oct-1995: Serge V.Vakulenko <vak@cronyx.ru> 17 * New eject algorithm. 18 * Some code style reformatting. 19 */ 20 21 #ifndef lint 22 static const char rcsid[] = 23 "$FreeBSD$"; 24 #endif /* not lint */ 25 26 #include <sys/cdio.h> 27 #include <sys/cdrio.h> 28 #include <sys/file.h> 29 #include <sys/ioctl.h> 30 #include <sys/param.h> 31 #include <arpa/inet.h> 32 #include <ctype.h> 33 #include <err.h> 34 #include <errno.h> 35 #include <histedit.h> 36 #include <limits.h> 37 #include <paths.h> 38 #include <stdio.h> 39 #include <stdlib.h> 40 #include <string.h> 41 #include <unistd.h> 42 #include <vis.h> 43 44 #define VERSION "2.0" 45 46 #define ASTS_INVALID 0x00 /* Audio status byte not valid */ 47 #define ASTS_PLAYING 0x11 /* Audio play operation in progress */ 48 #define ASTS_PAUSED 0x12 /* Audio play operation paused */ 49 #define ASTS_COMPLETED 0x13 /* Audio play operation successfully completed */ 50 #define ASTS_ERROR 0x14 /* Audio play operation stopped due to error */ 51 #define ASTS_VOID 0x15 /* No current audio status to return */ 52 53 #ifndef DEFAULT_CD_DRIVE 54 # define DEFAULT_CD_DRIVE "/dev/cd0c" 55 #endif 56 57 #ifndef DEFAULT_CD_PARTITION 58 # define DEFAULT_CD_PARTITION "c" 59 #endif 60 61 #define CMD_DEBUG 1 62 #define CMD_EJECT 2 63 #define CMD_HELP 3 64 #define CMD_INFO 4 65 #define CMD_PAUSE 5 66 #define CMD_PLAY 6 67 #define CMD_QUIT 7 68 #define CMD_RESUME 8 69 #define CMD_STOP 9 70 #define CMD_VOLUME 10 71 #define CMD_CLOSE 11 72 #define CMD_RESET 12 73 #define CMD_SET 13 74 #define CMD_STATUS 14 75 #define CMD_CDID 15 76 #define CMD_NEXT 16 77 #define CMD_PREVIOUS 17 78 #define CMD_SPEED 18 79 #define STATUS_AUDIO 0x1 80 #define STATUS_MEDIA 0x2 81 #define STATUS_VOLUME 0x4 82 83 struct cmdtab { 84 int command; 85 const char *name; 86 unsigned min; 87 const char *args; 88 } cmdtab[] = { 89 { CMD_CLOSE, "close", 1, "" }, 90 { CMD_DEBUG, "debug", 1, "on | off" }, 91 { CMD_EJECT, "eject", 1, "" }, 92 { CMD_HELP, "?", 1, 0 }, 93 { CMD_HELP, "help", 1, "" }, 94 { CMD_INFO, "info", 1, "" }, 95 { CMD_NEXT, "next", 1, "" }, 96 { CMD_PAUSE, "pause", 2, "" }, 97 { CMD_PLAY, "play", 1, "min1:sec1[.fram1] [min2:sec2[.fram2]]" }, 98 { CMD_PLAY, "play", 1, "track1[.index1] [track2[.index2]]" }, 99 { CMD_PLAY, "play", 1, "tr1 m1:s1[.f1] [[tr2] [m2:s2[.f2]]]" }, 100 { CMD_PLAY, "play", 1, "[#block [len]]" }, 101 { CMD_PREVIOUS, "previous", 2, "" }, 102 { CMD_QUIT, "quit", 1, "" }, 103 { CMD_RESET, "reset", 4, "" }, 104 { CMD_RESUME, "resume", 1, "" }, 105 { CMD_SET, "set", 2, "msf | lba" }, 106 { CMD_STATUS, "status", 1, "[audio | media | volume]" }, 107 { CMD_STOP, "stop", 3, "" }, 108 { CMD_VOLUME, "volume", 1, 109 "<l> <r> | left | right | mute | mono | stereo" }, 110 { CMD_CDID, "cdid", 2, "" }, 111 { CMD_SPEED, "speed", 2, "speed" }, 112 { 0, NULL, 0, NULL } 113 }; 114 115 struct cd_toc_entry toc_buffer[100]; 116 117 const char *cdname; 118 int fd = -1; 119 int verbose = 1; 120 int msf = 1; 121 122 int setvol(int, int); 123 int read_toc_entrys(int); 124 int play_msf(int, int, int, int, int, int); 125 int play_track(int, int, int, int); 126 int get_vol(int *, int *); 127 int status(int *, int *, int *, int *); 128 int open_cd(void); 129 int next_prev(char *arg, int); 130 int play(char *arg); 131 int info(char *arg); 132 int cdid(void); 133 int pstatus(char *arg); 134 char *input(int *); 135 void prtrack(struct cd_toc_entry *e, int lastflag); 136 void lba2msf(unsigned long lba, u_char *m, u_char *s, u_char *f); 137 unsigned int msf2lba(u_char m, u_char s, u_char f); 138 int play_blocks(int blk, int len); 139 int run(int cmd, char *arg); 140 char *parse(char *buf, int *cmd); 141 void help(void); 142 void usage(void); 143 char *use_cdrom_instead(const char *); 144 __const char *strstatus(int); 145 static u_int dbprog_discid(void); 146 __const char *cdcontrol_prompt(void); 147 148 void help () 149 { 150 struct cmdtab *c; 151 const char *s; 152 char n; 153 int i; 154 155 for (c=cmdtab; c->name; ++c) { 156 if (!
