The meaning of the codes is approximately 26 ** as follows: 27 ** 28 ** EX_USAGE -- The command was used incorrectly, e.g., with 29 ** the wrong number of arguments, a bad flag, a bad 30 ** syntax in a parameter, or whatever. 31 ** EX_DATAERR -- The input data was incorrect in some way. 32 ** This should only be used for user's data & not 33 ** system files. 34 ** EX_NOINPUT -- An input file (not a system file) did not 35 ** exist or was not readable. This could also include 36 ** errors like "No message" to a mailer (if it cared 37 ** to catch it). 38 ** EX_NOUSER -- The user specified did not exist. This might 39 ** be used for mail addresses or remote logins. 40 ** EX_NOHOST -- The host specified did not exist. This is used 41 ** in mail addresses or network requests. 42 ** EX_UNAVAILABLE -- A service is unavailable. This can occur 43 ** if a support program or file does not exist. This 44 ** can also be used as a catchall message when something 45 ** you wanted to do doesn't work, but you don't know 46 ** why. 47 ** EX_SOFTWARE -- An internal software error has been detected. 48 ** This should be limited to non-operating system related 49 ** errors as possible. 50 ** EX_OSERR -- An operating system error has been detected. 51 ** This is intended to be used for such things as "cannot 52 ** fork", "cannot create pipe", or the like. It includes 53 ** things like getuid returning a user that does not 54 ** exist in the passwd file. 55 ** EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp, 56 ** etc.) does not exist, cannot be opened, or has some 57 ** sort of error (e.g., syntax error). 58 ** EX_CANTCREAT -- A (user specified) output file cannot be 59 ** created. 60 ** EX_IOERR -- An error occurred while doing I/O on some file. 61 ** EX_TEMPFAIL -- temporary failure, indicating something that 62 ** is not really an error. In sendmail, this means 63 ** that a mailer (e.g.) could not create a connection, 64 ** and the request should be reattempted later. 65 ** EX_PROTOCOL -- the remote system returned something that 66 ** was "not possible" during a protocol exchange. 67 ** EX_NOPERM -- You did not have sufficient permission to 68 ** perform the operation. This is not intended for 69 ** file system problems, which should use NOINPUT or 70 ** CANTCREAT, but rather for higher level permissions. 71 */ 72 73 # define EX_OK 0 /* successful termination */ 74 75 # define EX__BASE 64 /* base value for error messages */ 76 77 # define EX_USAGE 64 /* command line usage error */ 78 # define EX_DATAERR 65 /* data format error */ 79 # define EX_NOINPUT 66 /* cannot open input */ 80 # define EX_NOUSER 67 /* addressee unknown */ 81 # define EX_NOHOST 68 /* host name unknown */ 82 # define EX_UNAVAILABLE 69 /* service unavailable */ 83 # define EX_SOFTWARE 70 /* internal software error */ 84 # define EX_OSERR 71 /* system error (e.g., can't fork) */ 85 # define EX_OSFILE 72 /* critical OS file missing */ 86 # define EX_CANTCREAT 73 /* can't create (user) output file */ 87 # define EX_IOERR 74 /* input/output error */ 88 # define EX_TEMPFAIL 75 /* temp failure; user is invited to retry */ 89 # define EX_PROTOCOL 76 /* remote error in protocol */ 90 # define EX_NOPERM 77 /* permission denied */ 91 # define EX_CONFIG 78 /* configuration error */ 92 93 # define EX__MAX 78 /* maximum listed value */ 94 95 #endif /* ! _SYSEXITS_H_ */ 96
