The meaning of the codes is approximately + * as follows: + * + * EX_USAGE -- The command was used incorrectly, e.g., with + * the wrong number of arguments, a bad flag, a bad + * syntax in a parameter, or whatever. + * EX_DATAERR -- The input data was incorrect in some way. + * This should only be used for user's data & not + * system files. + * EX_NOINPUT -- An input file (not a system file) did not + * exist or was not readable. This could also include + * errors like "No message" to a mailer (if it cared + * to catch it). + * EX_NOUSER -- The user specified did not exist. This might + * be used for mail addresses or remote logins. + * EX_NOHOST -- The host specified did not exist. This is used + * in mail addresses or network requests. + * EX_UNAVAILABLE -- A service is unavailable. This can occur + * if a support program or file does not exist. This + * can also be used as a catchall message when something + * you wanted to do doesn't work, but you don't know + * why. + * EX_SOFTWARE -- An internal software error has been detected. + * This should be limited to non-operating system related + * errors as possible. + * EX_OSERR -- An operating system error has been detected. + * This is intended to be used for such things as "cannot + * fork", "cannot create pipe", or the like. It includes + * things like getuid returning a user that does not + * exist in the passwd file. + * EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp, + * etc.) does not exist, cannot be opened, or has some + * sort of error (e.g., syntax error). + * EX_CANTCREAT -- A (user specified) output file cannot be + * created. + * EX_IOERR -- An error occurred while doing I/O on some file. + * EX_TEMPFAIL -- temporary failure, indicating something that + * is not really an error. In sendmail, this means + * that a mailer (e.g.) could not create a connection, + * and the request should be reattempted later. + * EX_PROTOCOL -- the remote system returned something that + * was "not possible" during a protocol exchange. + * EX_NOPERM -- You did not have sufficient permission to + * perform the operation. This is not intended for + * file system problems, which should use NOINPUT or + * CANTCREAT, but rather for higher level permissions. + */ + +#define EX_OK 0 /* successful termination */ + +#define EX__BASE 64 /* base value for error messages */ + +#define EX_USAGE 64 /* command line usage error */ +#define EX_DATAERR 65 /* data format error */ +#define EX_NOINPUT 66 /* cannot open input */ +#define EX_NOUSER 67 /* addressee unknown */ +#define EX_NOHOST 68 /* host name unknown */ +#define EX_UNAVAILABLE 69 /* service unavailable */ +#define EX_SOFTWARE 70 /* internal software error */ +#define EX_OSERR 71 /* system error (e.g., can't fork) */ +#define EX_OSFILE 72 /* critical OS file missing */ +#define EX_CANTCREAT 73 /* can't create (user) output file */ +#define EX_IOERR 74 /* input/output error */ +#define EX_TEMPFAIL 75 /* temp failure; user is invited to retry */ +#define EX_PROTOCOL 76 /* remote error in protocol */ +#define EX_NOPERM 77 /* permission denied */ +#define EX_CONFIG 78 /* configuration error */ + +#define EX__MAX 78 /* maximum listed value */ + +#endif /* sysexits.h */ |
