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 */
