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 * 13-Dec-1999: Knut A. Syed <kas@kas.no> 21 * Volume-command modified. If used with only one 22 * parameter it now sets both channels. If used without 23 * parameters it will print volume-info. 24 * Version 2.0.1 25 * 26 * 27-Jun-2008 Pietro Cerutti <gahr@FreeBSD.org> 27 * Further enhancement to volume. Values not in range 0-255 28 * are now reduced to be in range. This prevents overflow in 29 * the uchar storing the volume (256 -> 0, -20 -> 236, ...). 30 * Version 2.0.2 31 * 32 */ 33 34 #include <sys/cdefs.h> 35 __FBSDID("$FreeBSD$"); 36 37 #include <sys/cdio.h> 38 #include <sys/cdrio.h> 39 #include <sys/file.h> 40 #include <sys/ioctl.h> 41 #include <sys/param.h> 42 #include <arpa/inet.h> 43 #include <ctype.h> 44 #include <err.h> 45 #include <errno.h> 46 #include <histedit.h> 47 #include <limits.h> 48 #include <paths.h> 49 #include <stdio.h> 50 #include <stdlib.h> 51 #include <string.h> 52 #include <unistd.h> 53 #include <vis.h> 54 55 #define VERSION "2.0.2" 56 57 #define ASTS_INVALID 0x00 /* Audio status byte not valid */ 58 #define ASTS_PLAYING 0x11 /* Audio play operation in progress */ 59 #define ASTS_PAUSED 0x12 /* Audio play operation paused */ 60 #define ASTS_COMPLETED 0x13 /* Audio play operation successfully completed */ 61 #define ASTS_ERROR 0x14 /* Audio play operation stopped due to error */ 62 #define ASTS_VOID 0x15 /* No current audio status to return */ 63 64 #ifdef DEFAULT_CD_DRIVE 65 # error "Setting DEFAULT_CD_DRIVE is no longer supported" 66 #endif 67 68 #define CMD_DEBUG 1 69 #define CMD_EJECT 2 70 #define CMD_HELP 3 71 #define CMD_INFO 4 72 #define CMD_PAUSE 5 73 #define CMD_PLAY 6 74 #define CMD_QUIT 7 75 #define CMD_RESUME 8 76 #define CMD_STOP 9 77 #define CMD_VOLUME 10 78 #define CMD_CLOSE 11 79 #define CMD_RESET 12 80 #define CMD_SET 13 81 #define CMD_STATUS 14 82 #define CMD_CDID 15 83 #define CMD_NEXT 16 84 #define CMD_PREVIOUS 17 85 #define CMD_SPEED 18 86 #define STATUS_AUDIO 0x1 87 #define STATUS_MEDIA 0x2 88 #define STATUS_VOLUME 0x4 89 90 static struct cmdtab { 91 int command; 92 const char *name; 93 unsigned min; 94 const char *args; 95 } cmdtab[] = { 96 { CMD_CLOSE, "close", 1, "" }, 97 { CMD_DEBUG, "debug", 1, "on | off" }, 98 { CMD_EJECT, "eject", 1, "" }, 99 { CMD_HELP, "?", 1, 0 }, 100 { CMD_HELP, "help", 1, "" }, 101 { CMD_INFO, "info", 1, "" }, 102 { CMD_NEXT, "next", 1, "" }, 103 { CMD_PAUSE, "pause", 2, "" }, 104 { CMD_PLAY, "play", 1, "min1:sec1[.fram1] [min2:sec2[.fram2]]" }, 105 { CMD_PLAY, "play", 1, "track1[.index1] [track2[.index2]]" }, 106 { CMD_PLAY, "play", 1, "tr1 m1:s1[.f1] [[tr2] [m2:s2[.f2]]]" }, 107 { CMD_PLAY, "play", 1, "[#block [len]]" }, 108 { CMD_PREVIOUS, "previous", 2, "" }, 109 { CMD_QUIT, "quit", 1, "" }, 110 { CMD_RESET, "reset", 4, "" }, 111 { CMD_RESUME, "resume", 1, "" }, 112 { CMD_SET, "set", 2, "msf | lba" }, 113 { CMD_STATUS, "status", 1, "[audio | media | volume]" }, 114 { CMD_STOP, "stop", 3, "" }, 115 { CMD_VOLUME, "volume", 1, 116 "<l&r> <l> <r> | left | right | mute | mono | stereo" }, 117 { CMD_CDID, "cdid", 2, "" }, 118 { CMD_SPEED, "speed", 2, "speed" }, 119 { 0, NULL, 0, NULL } 120 }; 121 122 static struct cd_toc_entry toc_buffer[100]; 123 124 static const char *cdname; 125 static int fd = -1; 126 static int verbose = 1; 127 static int msf = 1; 128 129 static int setvol(int, int); 130 static int read_toc_entrys(int); 131 static int play_msf(int, int, int, int, int, int); 132 static int play_track(int, int, int, int); 133 static int status(int *, int *, int *, int *); 134 static int open_cd(void); 135 static int next_prev(char *arg, int); 136 static int play(char *arg); 137 static int info(char *arg); 138 static int cdid(void); 139 static int pstatus(char *arg); 140 static char *input(int *); 141 static void prtrack(struct cd_toc_entry *e, int lastflag); 142 static void lba2msf(unsigned long lba, u_char *m, u_char *s, u_char *f); 143 static unsigned int msf2lba(u_char m, u_char s, u_char f); 144 static int play_blocks(int blk, int len); 145 static int run(int cmd, char *arg); 146 static char *parse(char *buf, int *cmd); 147 static void help(void); 148 static void usage(void); 149 static char *use_cdrom_instead(const char *); 150 static const char *strstatus(int); 151 static u_int dbprog_discid(void); 152 static const char *cdcontrol_prompt(void); 153 154 static void 155 help(void) 156 { 157 struct cmdtab *c; 158 const char *s; 159 char n; 160 int i; 161 162 for (c=cmdtab; c->name; ++c) { 163 if (!
