This package provides a server for locks and a package for clients to access that server. The result is that clients can access named locks on a Internet wide bases, solving critical section problems without the mess of NFS or other file locking techniques.

IPC::MM provides an interface to Ralf Engelschall's mm library, allowing memory to be shared between multiple processes in a relatively convenient way. IPC::MM provides methods to create and destroy shared memory segments and to access data structures within those shared memory segments, as well as miscellaneous methods. Additionally, it provides a tied interface for scalars and hashes.

Perl extension for accessing a JVM remotely or locally

IPC::MMA provides an interface to Ralf Engelschall's mm library, allowing memory to be shared between multiple processes in a relatively convenient way. IPC::MMA is a superset of Arthur Choung's IPC::MM module, adding arrays and allowing any Perl scalar to be used as a hash/BTree key rather than just C strings. IPC::MMA hashes are like IPC::MM BTrees in that they return keys in sorted order ineach, keys, and next operations. An IPC::MMA array can store data in any of six ways, including general-purpose scalars, signed or unsigned integers, floating-point numbers, fixed-length strings/records, and booleans at one bit per array element.

The IPC::Mmap::Share was born out of the need to share structures among processes that come from the same ancestor. It tries to do so in a very simple and straightforward manner. Just create an IPC::Mmap::Share object, and use set to store your data and get to get it back.

This module allows you to alias a lexical variable to another variable (package or lexical). You will receive a fatal error if you try aliasing a scalar to something that is not a scalar etc.

LV makes lvalue subroutines easy and practical to use. It's inspired by the lvalue module which is sadly problematic because of the existence of another module on CPAN called Lvalue. (They can get confused on file-systems that have case-insensitive file names.) LV comes with three different implementations, based on Variable::Magic, Sentinel and tie; it will choose and use the best available one. You can force LV to pick a particular implementation using: $ENV{PERL_LV_IMPLEMENTATION} = 'Magic'; # or 'Sentinel' or 'Tie' The tie implementation is the slowest, but will work on Perl 5.6 with only core modules.

This module provides a simple API for publishing messages to channels and for subscribing to them. When a message is published on a channel, all subscribers currently in that channel will get it on their next "get" or "get_all" call. Currently, it offers three backends: "DBM_Deep" for on-disk storage, "Memcached" for possibly multi-host storage, and "PlainHash" for single-process storage.

IPC::Run allows you run and interact with child processes, files, pipes, and pseudo-ttys. Both event-loop and procedural techniques are supported and may be mixed. Likewise, functional and OO API styles are both supported and may be mixed.

IPC::Shareable allows you to tie a variable to shared memory making it easy to share the contents of that variable with other Perl processes. Currently either scalars or hashes can be tied; tying of arrays remains a work in progress. However, the variable being tied may contain arbitrarily complex data structures - including references to arrays, hashes of hashes, etc. See the "REFERENCES" entry in this man page below for more information.
