Hi all,
I'm trying to do a proof of concept for myself using MLDBM of basically
trying to add two records to a hash. ATM I have the following code
#!/usr/bin/perl
use strict ;
use warnings ;
use MLDBM;
use Fcntl ;
my %hash ;
my $filename = "/tmp/filt" ;
unlink $filename ;
my $db = tie(%hash, 'MLDBM', $filename, O_RDRW|O_EXLOCK, 0640) or die
("Cannot open $filename: $!\n");
%hash = ( '1' => { url => "www.slashdot.org" , title => "News for
nerds" , lastvisit =>" 100000" } );
%hash .= ( '2' => { url => "www.slashdot.org" , title => "News for
nerds" , lastvisit =>" 100000" } );
print Data::Dumper->Dump ( [\%hash ]);
undef $db;
untie %hash;
and I'm getting
Can't modify private hash in concatenation (.) or string at ./perldbm line
15, near ");"
As such what do I have to do to add entries to the hash (without defining
it all in one hash?) The reason is that I want to writ eaprorgam that will
add a hash each time it is run so just trying to do it on a simple prog
ATM
