A very quick and easy to use way to communicate between programs.

The hostile reviews ignore issues like platform dependence.
If they can't find a bug by reading the code, maybe the underlying system calls are faulty on their computer.
The module obviously requires a fully working SysV IPC on the machine.

The criticism that it only supports scalars is not a problem if you use it with Storable as suggested in the documentation, which I have done.

If something very elaborate is required, this Lite module is not the right one to use:-)

If you want to destroy the share on exit, you may want a signal handler and to undef the share in an END subroutine.
The destroy method only takes numeric flag, unlike the destroy option.

This module is broken.


The documentation is pretty good , and I have read its code , however ,
I wanted to write a Object Monitor class for it that would track instances of objects of a class over multiple processes and I could not.
With a fair amount of sincerity I can firmly decide that this module is broken.
Upon request I can provide a test case on which the module clearly is out of control.
It presented irreproducible results with weird errors like

Use of uninitialized value in subroutine entry at /usr/local/lib/perl/5.10.0/IPC/ShareLite.pm line 304 during global destruction.
(in cleanup) IPC::ShareLite::read_share: share is not of type SharePtr at /usr/local/lib/perl/5.10.0/IPC/ShareLite.pm line 304 during global destruction

Sometimes it presented this error, sometime it didn't.
There was no pattern , or anything that I could hold on to in fixing the error.
Again , upon request , I will provide the necessary code to prove that the module is broken .

It's a pitty because at the time I'm writing this it would've been really useful for me.


UPDATE:
I'd like to mention that the place I had most trobule with was accessing the shared memory area inside the destructor DESTROY.
I don't know if this is possible or not , documented or undocumented but it should be documented anyway.

Excellent little module. The only shortcoming this far is that it does not handle data other than scalars.
