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