ARSperl Manual - Special Variables

## Special Variables

`$ars_errstr`
  Error, warning and informational messages from the C or Perl API are placed in this variable. This variable is not a ``real'' variable. Instead, it is built on the fly whenever you reference it. It is built from `ars_errhash`

`%ars_errhash`
  Error, warning and informational messages from the C or Perl API are placed in this hash. The hash contains several array references, allowing multiple messages to be handled. The easiest way to access this variable is to just reference (print, etc) the `$ars_errstr` variable which is contructed on the fly from the contents of this hash's components. See Also: Error Hash Values.
