The meaning of the codes is approximately 26 * as follows: 27 * 28 * EX_USAGE -- The command was used incorrectly, e.g., with 29 * the wrong number of arguments, a bad flag, a bad 30 * syntax in a parameter, or whatever. 31 * EX_DATAERR -- The input data was incorrect in some way. 32 * This should only be used for user's data & not 33 * system files. 34 * EX_NOINPUT -- An input file (not a system file) did not 35 * exist or was not readable. This could also include 36 * errors like "No message" to a mailer (if it cared 37 * to catch it). 38 * EX_NOUSER -- The user specified did not exist. This might 39 * be used for mail addresses or remote logins. 40 * EX_NOHOST -- The host specified did not exist. This is used 41 * in mail addresses or network requests. 42 * EX_UNAVAILABLE -- A service is unavailable. This can occur 43 * if a support program or file does not exist. This 44 * can also be used as a catchall message when something 45 * you wanted to do doesn't work, but you don't know 46 * why. 47 * EX_SOFTWARE -- An internal software error has been detected. 48 * This should be limited to non-operating system related 49 * errors as possible. 50 * EX_OSERR -- An operating system error has been detected. 51 * This is intended to be used for such things as "cannot 52 * fork", "cannot create pipe", or the like. It includes 53 * things like getuid returning a user that does not 54 * exist in the passwd file. 55 * EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp, 56 * etc.) does not exist, cannot be opened, or has some 57 * sort of error (e.g., syntax error). 58 * EX_CANTCREAT -- A (user specified) output file cannot be 59 * created. 60 * EX_IOERR -- An error occurred while doing I/O on some file. 61 * EX_TEMPFAIL -- temporary failure, indicating something that 62 * is not really an error. In sendmail, this means 63 * that a mailer (e.g.) could not create a connection, 64 * and the request should be reattempted later. 65 * EX_PROTOCOL -- the remote system returned something that 66 * was "not possible" during a protocol exchange. 67 * EX_NOPERM -- You did not have sufficient permission to 68 * perform the operation. This is not intended for 69 * file system problems, which should use NOINPUT or 70 * CANTCREAT, but rather for higher level permissions. 71 */ 72 73 #define EX_OK 0 /* successful termination */ 74 75 #define EX__BASE 64 /* base value for error messages */ 76 77 #define EX_USAGE 64 /* command line usage error */ 78 #define EX_DATAERR 65 /* data format error */ 79 #define EX_NOINPUT 66 /* cannot open input */ 80 #define EX_NOUSER 67 /* addressee unknown */ 81 #define EX_NOHOST 68 /* host name unknown */ 82 #define EX_UNAVAILABLE 69 /* service unavailable */ 83 #define EX_SOFTWARE 70 /* internal software error */ 84 #define EX_OSERR 71 /* system error (e.g., can't fork) */ 85 #define EX_OSFILE 72 /* critical OS file missing */ 86 #define EX_CANTCREAT 73 /* can't create (user) output file */ 87 #define EX_IOERR 74 /* input/output error */ 88 #define EX_TEMPFAIL 75 /* temp failure; user is invited to retry */ 89 #define EX_PROTOCOL 76 /* remote error in protocol */ 90 #define EX_NOPERM 77 /* permission denied */ 91 #define EX_CONFIG 78 /* configuration error */ 92 93 #define EX__MAX 78 /* maximum listed value */ 94 95 #endif /* ! _SYSEXITS_H_ */ 96
