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. */ # if SM_CONF_SYSEXITS_H # include <sysexits.h> # else /* SM_CONF_SYSEXITS_H */ # 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 /* SM_CONF_SYSEXITS_H */ extern char *sm_strexit __P((int)); extern char *sm_sysexitmsg __P((int)); extern char *sm_sysexmsg __P((int)); #endif /* !
