8.35. CGI::Carp

Creates Carp-like CGI routines for
writing error messages to the HTTPD or other error log. Exports
functions for warn, die,
carp, confess, and
croak. The functions write timestamped error
messages to your server log or other output that you specify. See Section 8.32, "Carp" for details on
the Carp functions.

Two other functions are provided by this module. Neither are
automatically exported, so you must explicitly import them in
use:

use CGI::Carp qw(carpout fatalsToBrowser);

carpout \*fh

Sends error messages to the filehandle fh.
You should provide a reference to the filehandle
glob, although you can also just use the
filehandle's name for this function.

fatalsToBrowser

When this routine is imported via use, fatal
errors, such as those produced by die and
confess, send error messages to the browser as
well as the error log. A simple HTTP response is created with the
error message, followed by a request to send mail to the web
administrator.
