The meaning of the codes is approximately 47 * as follows: 48 * 49 * EX_USAGE -- The command was used incorrectly, e.g., with 50 * the wrong number of arguments, a bad flag, a bad 51 * syntax in a parameter, or whatever. 52 * EX_DATAERR -- The input data was incorrect in some way. 53 * This should only be used for user's data & not 54 * system files. 55 * EX_NOINPUT -- An input file (not a system file) did not 56 * exist or was not readable. This could also include 57 * errors like "No message" to a mailer (if it cared 58 * to catch it). 59 * EX_NOUSER -- The user specified did not exist. This might 60 * be used for mail addresses or remote logins. 61 * EX_NOHOST -- The host specified did not exist. This is used 62 * in mail addresses or network requests. 63 * EX_UNAVAILABLE -- A service is unavailable. This can occur 64 * if a support program or file does not exist. This 65 * can also be used as a catchall message when something 66 * you wanted to do doesn't work, but you don't know 67 * why. 68 * EX_SOFTWARE -- An internal software error has been detected. 69 * This should be limited to non-operating system related 70 * errors as possible. 71 * EX_OSERR -- An operating system error has been detected. 72 * This is intended to be used for such things as "cannot 73 * fork", "cannot create pipe", or the like. It includes 74 * things like getuid returning a user that does not 75 * exist in the passwd file. 76 * EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp, 77 * etc.) does not exist, cannot be opened, or has some 78 * sort of error (e.g., syntax error). 79 * EX_CANTCREAT -- A (user specified) output file cannot be 80 * created. 81 * EX_IOERR -- An error occurred while doing I/O on some file. 82 * EX_TEMPFAIL -- temporary failure, indicating something that 83 * is not really an error. In sendmail, this means 84 * that a mailer (e.g.) could not create a connection, 85 * and the request should be reattempted later. 86 * EX_PROTOCOL -- the remote system returned something that 87 * was "not possible" during a protocol exchange. 88 * EX_NOPERM -- You did not have sufficient permission to 89 * perform the operation. This is not intended for 90 * file system problems, which should use NOINPUT or 91 * CANTCREAT, but rather for higher level permissions. 92 */ 93 94 #define EX_OK 0 /* successful termination */ 95 96 #define EX__BASE 64 /* base value for error messages */ 97 98 #define EX_USAGE 64 /* command line usage error */ 99 #define EX_DATAERR 65 /* data format error */ 100 #define EX_NOINPUT 66 /* cannot open input */ 101 #define EX_NOUSER 67 /* addressee unknown */ 102 #define EX_NOHOST 68 /* host name unknown */ 103 #define EX_UNAVAILABLE 69 /* service unavailable */ 104 #define EX_SOFTWARE 70 /* internal software error */ 105 #define EX_OSERR 71 /* system error (e.g., can't fork) */ 106 #define EX_OSFILE 72 /* critical OS file missing */ 107 #define EX_CANTCREAT 73 /* can't create (user) output file */ 108 #define EX_IOERR 74 /* input/output error */ 109 #define EX_TEMPFAIL 75 /* temp failure; user is invited to retry */ 110 #define EX_PROTOCOL 76 /* remote error in protocol */ 111 #define EX_NOPERM 77 /* permission denied */ 112 #define EX_CONFIG 78 /* configuration error */ 113 114 #define EX__MAX 78 /* maximum listed value */ 115 116 #endif /* !_SYSEXITS_H_ */ 117
