Shared memory can happen in IPC, too. What isn't shared between processes is file/socket handles. Theoretically, you can copy a file handle from one process to another, but the procedure for doing so without resorting to fork() makes me smell burnt toast... Threads of course don't have this problem, they share everything.
IPC is also a can of worms in some ways, their synchronization primitives have read/write bits just like files do, if you're not building your own private client/server model they can be more complicated than needed.

rt::client::rest::attachment
RT::Client::REST::Attachment(3pm) User Contributed Perl Documentation RT::Client::REST::Attachment(3pm)
NAME
RT::Client::REST::Attachment -- this object represents an attachment.
SYNOPSIS
my $attachments = $ticket->attachments;
my $count = $attachments->count;
print "There are $count attachments.
";
my $iterator = $attachments->get_iterator;
while (my $att = &$iterator) {
print "Id: ", $att->id, "; Subject: ", $att->subject, "
";
}
DESCRIPTION
An attachment is a second-class citizen, as it does not exist (at least from the current REST protocol implementation) by itself. At the
moment, it is always associated with a ticket (see parent_id attribute). Thus, you will rarely retrieve an attachment by itself; instead,
you should use "attachments()" method of RT::Client::REST::Ticket object to get an iterator for all attachments for that ticket.
ATTRIBUTES
id
Numeric ID of the attachment.
creator_id
Numeric ID of the user who created the attachment.
parent_id
Numeric ID of the object the attachment is associated with. This is not a proper attribute of the attachment as specified by REST -- it
is simply to store the ID of the RT::Client::REST::Ticket object this attachment belongs to.
subject
Subject of the attachment.
content_type
Content type.
file_name
File name (if any).
transaction_id
Numeric ID of the RT::Client::REST::Transaction object this attachment is associated with.
message_id
Message ID.
created
Time when the attachment was created
content
Actual content of the attachment.
headers
Headers (not parsed), if any.
parent
Parent (not sure what this is yet).
content_encoding
Content encoding, if any.
METHODS
RT::Client::REST::Attachment is a read-only object, so you cannot "store()" it. Also, because it is a second-class citizen, you cannot
"search()" or "count()" it -- use "attachments()" method provided by RT::Client::REST::Ticket.
retrieve
To retrieve an attachment, attributes id and parent_id must be set.
INTERNAL METHODS
rt_type
Returns 'attachment'.
SEE ALSO
RT::Client::REST::Ticket, RT::Client::REST::SearchResult.
