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