The meaning of the codes is approximately 51 * as follows: 52 * 53 * EX_USAGE -- The command was used incorrectly, e.g., with 54 * the wrong number of arguments, a bad flag, a bad 55 * syntax in a parameter, or whatever. 56 * EX_DATAERR -- The input data was incorrect in some way. 57 * This should only be used for user's data & not 58 * system files. 59 * EX_NOINPUT -- An input file (not a system file) did not 60 * exist or was not readable. This could also include 61 * errors like "No message" to a mailer (if it cared 62 * to catch it). 63 * EX_NOUSER -- The user specified did not exist. This might 64 * be used for mail addresses or remote logins. 65 * EX_NOHOST -- The host specified did not exist. This is used 66 * in mail addresses or network requests. 67 * EX_UNAVAILABLE -- A service is unavailable. This can occur 68 * if a support program or file does not exist. This 69 * can also be used as a catchall message when something 70 * you wanted to do doesn't work, but you don't know 71 * why. 72 * EX_SOFTWARE -- An internal software error has been detected. 73 * This should be limited to non-operating system related 74 * errors as possible. 75 * EX_OSERR -- An operating system error has been detected. 76 * This is intended to be used for such things as "cannot 77 * fork", "cannot create pipe", or the like. It includes 78 * things like getuid returning a user that does not 79 * exist in the passwd file. 80 * EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp, 81 * etc.) does not exist, cannot be opened, or has some 82 * sort of error (e.g., syntax error). 83 * EX_CANTCREAT -- A (user specified) output file cannot be 84 * created. 85 * EX_IOERR -- An error occurred while doing I/O on some file. 86 * EX_TEMPFAIL -- temporary failure, indicating something that 87 * is not really an error. In sendmail, this means 88 * that a mailer (e.g.) could not create a connection, 89 * and the request should be reattempted later. 90 * EX_PROTOCOL -- the remote system returned something that 91 * was "not possible" during a protocol exchange. 92 * EX_NOPERM -- You did not have sufficient permission to 93 * perform the operation. This is not intended for 94 * file system problems, which should use NOINPUT or 95 * CANTCREAT, but rather for higher level permissions. 96 */ 97 98 #define EX_OK 0 /* successful termination */ 99 100 #define EX__BASE 64 /* base value for error messages */ 101 102 #define EX_USAGE 64 /* command line usage error */ 103 #define EX_DATAERR 65 /* data format error */ 104 #define EX_NOINPUT 66 /* cannot open input */ 105 #define EX_NOUSER 67 /* addressee unknown */ 106 #define EX_NOHOST 68 /* host name unknown */ 107 #define EX_UNAVAILABLE 69 /* service unavailable */ 108 #define EX_SOFTWARE 70 /* internal software error */ 109 #define EX_OSERR 71 /* system error (e.g., can't fork) */ 110 #define EX_OSFILE 72 /* critical OS file missing */ 111 #define EX_CANTCREAT 73 /* can't create (user) output file */ 112 #define EX_IOERR 74 /* input/output error */ 113 #define EX_TEMPFAIL 75 /* temp failure; user is invited to retry */ 114 #define EX_PROTOCOL 76 /* remote error in protocol */ 115 #define EX_NOPERM 77 /* permission denied */ 116 #define EX_CONFIG 78 /* configuration error */ 117 118 #define EX__MAX 78 /* maximum listed value */ 119 120 121 #endif 122 123 124 #endif /* !_SYSEXITS_H_ */ 125
