For example, perhaps it might be better to convert the hash to a string (using Data::Dumper) and it is the string that is stored in the shared-memory segment.
Personally, I use JSON to store my data. I like the ease of it, and its especially good because it's cross platform and stores well in files if you want to dump the data for future program runs. Here's a non-complete example:
use warnings;
use strict;
use JSON;
my $shared_memory_variable = ...; # Create shared mem with IPC::Sharea
+ble
my $data = {
a => 1,
b => [
1,
2,
3
],
c => {
z => 99,
y => 98,
x => {
m => 'hello, world!'
},
},
};
# Create JSON string and store it in the shared memory allocation
$shared_memory_variable = encode_json $data;
# Restore the shared memory JSON to a Perl data structure
my $perl = decode_json $shared_memory_variable;
