21 | ** SYSEXITS.H -- Exit status codes for system programs. | |
22 | ** | |
23 | ** This include file attempts to categorize possible error | |
24 | ** exit statuses for system programs, notably delivermail | |
25 | ** and the Berkeley network. | |
26 | ** | |
27 | ** Error numbers begin at EX__BASE to reduce the possibility of | |
28 | ** clashing with other exit statuses that random programs may | |
29 | ** already return. The meaning of the codes is approximately | |
30 | ** as follows: | |
31 | ** | |
32 | ** EX_USAGE -- The command was used incorrectly, e.g., with | |
33 | ** the wrong number of arguments, a bad flag, a bad | |
34 | ** syntax in a parameter, or whatever. | |
35 | ** EX_DATAERR -- The input data was incorrect in some way. | |
36 | ** This should only be used for user's data & not | |
37 | ** system files. | |
38 | ** EX_NOINPUT -- An input file (not a system file) did not | |
39 | ** exist or was not readable. This could also include | |
40 | ** errors like "No message" to a mailer (if it cared | |
41 | ** to catch it). | |
42 | ** EX_NOUSER -- The user specified did not exist. This might | |
43 | ** be used for mail addresses or remote logins. | |
44 | ** EX_NOHOST -- The host specified did not exist. This is used | |
45 | ** in mail addresses or network requests. | |
46 | ** EX_UNAVAILABLE -- A service is unavailable. This can occur | |
47 | ** if a support program or file does not exist. This | |
48 | ** can also be used as a catchall message when something | |
49 | ** you wanted to do doesn't work, but you don't know | |
50 | ** why. | |
51 | ** EX_SOFTWARE -- An internal software error has been detected. | |
52 | ** This should be limited to non-operating system related | |
53 | ** errors as possible. | |
54 | ** EX_OSERR -- An operating system error has been detected. | |
55 | ** This is intended to be used for such things as "cannot | |
56 | ** fork", "cannot create pipe", or the like. It includes | |
57 | ** things like getuid returning a user that does not | |
58 | ** exist in the passwd file. | |
59 | ** EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp, | |
60 | ** etc.) does not exist, cannot be opened, or has some | |
61 | ** sort of error (e.g., syntax error). | |
62 | ** EX_CANTCREAT -- A (user specified) output file cannot be | |
63 | ** created. | |
64 | ** EX_IOERR -- An error occurred while doing I/O on some file. | |
8476145b EA |
65 | ** EX_TEMPFAIL -- temporary failure, indicating something that |
66 | ** is not really an error. In sendmail, this means | |
67 | ** that a mailer (e.g.) could not create a connection, | |
68 | ** and the request should be reattempted later. | |
977ccbaf EA |
69 | ** EX_PROTOCOL -- the remote system returned something that |
70 | ** was "not possible" during a protocol exchange. | |
10c03b41 EA |
71 | ** EX_NOPERM -- You did not have sufficient permission to |
72 | ** perform the operation. This is not intended for | |
73 | ** file system problems, which should use NOINPUT or | |
74 | ** CANTCREAT, but rather for higher level permissions. | |
75 | ** For example, kre uses this to restrict who students | |
76 | ** can send mail to. | |
8476145b | 77 | ** |
977ccbaf | 78 | ** Maintained by Eric Allman (eric@berkeley, ucbvax!eric) -- |
8476145b | 79 | ** please mail changes to me. |
