It is a warning Perl gives on strict, if variables have 0 values or are
NULL.
The example below will trigger that warning:
###################################
#!/usr/sbin/perl -w
use strict;
Xyz (fist_value, second_value); # Here we call sub xyz with 2 arguments
Sub xyz {
my ($x,$y,$z)@_;
print $x;
print $y;
print $z; # This will trigger the warning, because $z has no value.
}
To arrest the warning, I may use something like this:
Print $z if $z;

Betreff: Apache::AuthCookie causing strange-"Use of uninitialized
value."
I use Apache::AuthCookie 3.04, which seems to be the latest version,
under
Apache/1.3.26 Ben-SSL/1.48 (Unix) Debian GNU/Linux PHP/4.1.2
mod_perl/1.26.
When I use "PerlFixupHandler Apache::AuthCookie->recognize_user", Apache
writes "Use of uninitialized value." in errorlog for each request and
subrequest. I have tried editing AuthCookie.pm, checking everything with
defined(), even substituting recognize_user with a stub function.
Still it is there. I am not sure it comes from perl, because perl use to
say "at line X" too. But from what else?
This has been up before, but no one answered it then:
