The meaning of the codes is approximately 53 * as follows: 54 * 55 * EX_USAGE -- The command was used incorrectly, e.g., with 56 * the wrong number of arguments, a bad flag, a bad 57 * syntax in a parameter, or whatever. 58 * EX_DATAERR -- The input data was incorrect in some way. 59 * This should only be used for user's data & not 60 * system files. 61 * EX_NOINPUT -- An input file (not a system file) did not 62 * exist or was not readable. This could also include 63 * errors like "No message" to a mailer (if it cared 64 * to catch it). 65 * EX_NOUSER -- The user specified did not exist. This might 66 * be used for mail addresses or remote logins. 67 * EX_NOHOST -- The host specified did not exist. This is used 68 * in mail addresses or network requests. 69 * EX_UNAVAILABLE -- A service is unavailable. This can occur 70 * if a support program or file does not exist. This 71 * can also be used as a catchall message when something 72 * you wanted to do doesn't work, but you don't know 73 * why. 74 * EX_SOFTWARE -- An internal software error has been detected. 75 * This should be limited to non-operating system related 76 * errors as possible. 77 * EX_OSERR -- An operating system error has been detected. 78 * This is intended to be used for such things as "cannot 79 * fork", "cannot create pipe", or the like. It includes 80 * things like getuid returning a user that does not 81 * exist in the passwd file. 82 * EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp, 83 * etc.) does not exist, cannot be opened, or has some 84 * sort of error (e.g., syntax error). 85 * EX_CANTCREAT -- A (user specified) output file cannot be 86 * created. 87 * EX_IOERR -- An error occurred while doing I/O on some file. 88 * EX_TEMPFAIL -- temporary failure, indicating something that 89 * is not really an error. In sendmail, this means 90 * that a mailer (e.g.) could not create a connection, 91 * and the request should be reattempted later. 92 * EX_PROTOCOL -- the remote system returned something that 93 * was "not possible" during a protocol exchange. 94 * EX_NOPERM -- You did not have sufficient permission to 95 * perform the operation. This is not intended for 96 * file system problems, which should use NOINPUT or 97 * CANTCREAT, but rather for higher level permissions. 98 */ 99 100 #define EX_OK 0 /* successful termination */ 101 102 #define EX__BASE 64 /* base value for error messages */ 103 104 #define EX_USAGE 64 /* command line usage error */ 105 #define EX_DATAERR 65 /* data format error */ 106 #define EX_NOINPUT 66 /* cannot open input */ 107 #define EX_NOUSER 67 /* addressee unknown */ 108 #define EX_NOHOST 68 /* host name unknown */ 109 #define EX_UNAVAILABLE 69 /* service unavailable */ 110 #define EX_SOFTWARE 70 /* internal software error */ 111 #define EX_OSERR 71 /* system error (e.g., can't fork) */ 112 #define EX_OSFILE 72 /* critical OS file missing */ 113 #define EX_CANTCREAT 73 /* can't create (user) output file */ 114 #define EX_IOERR 74 /* input/output error */ 115 #define EX_TEMPFAIL 75 /* temp failure; user is invited to retry */ 116 #define EX_PROTOCOL 76 /* remote error in protocol */ 117 #define EX_NOPERM 77 /* permission denied */ 118 #define EX_CONFIG 78 /* configuration error */ 119 120 #define EX__MAX 78 /* maximum listed value */ 121 122 #endif /* !_SYSEXITS_H_ */ 123
