The meaning of the codes is approximately 57 * as follows: 58 * 59 * EX_USAGE -- The command was used incorrectly, e.g., with 60 * the wrong number of arguments, a bad flag, a bad 61 * syntax in a parameter, or whatever. 62 * EX_DATAERR -- The input data was incorrect in some way. 63 * This should only be used for user's data & not 64 * system files. 65 * EX_NOINPUT -- An input file (not a system file) did not 66 * exist or was not readable. This could also include 67 * errors like "No message" to a mailer (if it cared 68 * to catch it). 69 * EX_NOUSER -- The user specified did not exist. This might 70 * be used for mail addresses or remote logins. 71 * EX_NOHOST -- The host specified did not exist. This is used 72 * in mail addresses or network requests. 73 * EX_UNAVAILABLE -- A service is unavailable. This can occur 74 * if a support program or file does not exist. This 75 * can also be used as a catchall message when something 76 * you wanted to do doesn't work, but you don't know 77 * why. 78 * EX_SOFTWARE -- An internal software error has been detected. 79 * This should be limited to non-operating system related 80 * errors as possible. 81 * EX_OSERR -- An operating system error has been detected. 82 * This is intended to be used for such things as "cannot 83 * fork", "cannot create pipe", or the like. It includes 84 * things like getuid returning a user that does not 85 * exist in the passwd file. 86 * EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp, 87 * etc.) does not exist, cannot be opened, or has some 88 * sort of error (e.g., syntax error). 89 * EX_CANTCREAT -- A (user specified) output file cannot be 90 * created. 91 * EX_IOERR -- An error occurred while doing I/O on some file. 92 * EX_TEMPFAIL -- temporary failure, indicating something that 93 * is not really an error. In sendmail, this means 94 * that a mailer (e.g.) could not create a connection, 95 * and the request should be reattempted later. 96 * EX_PROTOCOL -- the remote system returned something that 97 * was "not possible" during a protocol exchange. 98 * EX_NOPERM -- You did not have sufficient permission to 99 * perform the operation. This is not intended for 100 * file system problems, which should use NOINPUT or 101 * CANTCREAT, but rather for higher level permissions. 102 * 103 * Haiku recently added an #ifdef _BSD_SOURCE around the definitions, 104 * so we may need to #define things even though we did include the 105 * system's sysexits.h. 106 */ 107 108 #ifndef EX_OK 109 #define EX_OK 0 /* successful termination */ 110 #endif 111 112 #ifndef EX__BASE 113 #define EX__BASE 64 /* base value for error messages */ 114 115 #define EX_USAGE 64 /* command line usage error */ 116 #define EX_DATAERR 65 /* data format error */ 117 #define EX_NOINPUT 66 /* cannot open input */ 118 #define EX_NOUSER 67 /* addressee unknown */ 119 #define EX_NOHOST 68 /* host name unknown */ 120 #define EX_UNAVAILABLE 69 /* service unavailable */ 121 #define EX_SOFTWARE 70 /* internal software error */ 122 #define EX_OSERR 71 /* system error (e.g., can't fork) */ 123 #define EX_OSFILE 72 /* critical OS file missing */ 124 #define EX_CANTCREAT 73 /* can't create (user) output file */ 125 #define EX_IOERR 74 /* input/output error */ 126 #define EX_TEMPFAIL 75 /* temp failure; user is invited to retry */ 127 #define EX_PROTOCOL 76 /* remote error in protocol */ 128 #define EX_NOPERM 77 /* permission denied */ 129 #define EX_CONFIG 78 /* configuration error */ 130 131 #define EX_NOTFOUND 79 /* entry not found */ 132 #define EX__MAX 79 /* maximum listed value */ 133 #endif 134 135 #endif /* !_SCHILY_SYSEXITS_H */ 136
