Hello,

I'm trying to lock and unlock a variable in shared memory

my $cleanHandler = tie $cleanup_running, 'IPC::Shareable', 'data',
{ 'destroy' => 1, 'create' => 1 };


$cleanHandler->shlock();
$cleanup_running++;
$cleanHandler->shunlock();

Keep getting this error and can't understand the problem.

Use of uninitialized value $ice in substr at /usr/local/share/perl/
5.10.1/IPC/Shareable.pm line 542.#012

Any tips ?

Best regards,
FR

Hi,

I guess you should not really use IPC::Shareable, it's last release
was ages ago.
It does not succeed tests on a 5.10.x perl:
https://rt.cpan.org/Public/Bug/Display.html?id=3D41401 - and I guess the
patch in this bug report will get it working for you again.

I guess it would be worthwile finding a replacement module for
IPC::Shareable. You can try replacing it with
http://search.cpan.org/~mhx/IPC-SysV-2.03/lib/IPC/SharedMem. pm which
is still being maintained.

Hello,

My problem was that I was creating the SM variable and after a bit the app
was killing the current process witch destroyed the variable.

Sorry (very long script), and thanks for your help.
