/*

    Exit status codes for system programs.

        This include file attempts to categorize possible error

        exit statuses for system programs, notably delivermail

        and the Berkeley network.

        Error numbers begin at EX__BASE to reduce the possibility of

        clashing with other exit statuses that random programs may

        already return.  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.
