This module provides a shared memory cache accessed as a tied hash. Shared memory is an area of memory that is available to all processes. It is accessed by choosing a key, the ipc_key arguement to tie. Every process that accesses shared memory with ...

Provides set/reset locking methods which will force a critical region of code to run single threaded Implements a factory pattern, three implementations are provided. The LCD option IPC::SRLock::Fcntl which works on non Unixen, IPC::SRLock::Sysv whic...

IPC::ShareLite provides a simple interface to shared memory, allowing data to be efficiently communicated between processes. Your operating system must support SysV IPC (shared memory and semaphores) in order to use this module. IPC::ShareLite provid...

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. Scalars, arrays, and hashes can be tied. The variable being tied may contain arbitrarily complex data struct...

An abstract interface to semaphore sets and their resources. A semaphore is an abstract data type that is provided by the system to give access control to common resources by multiple processes in parallel programming or in a multi-user environment. ...

This module allows you to limit concurrency of specific portions of your code. It can be used to limit resource usage or to give exclusive access to specific resources. This module is similar in functionality to IPC::Concurrency with the main differe...

Global::IPC::StaticVariable is a module which can alloc 512MB Sysv IPC shared memory for perl. You can use it to delivery contents, or use it as a job queue. It can be updated with strings, or append into it, or get contents and clear it. And all of ...

A friend couldn't get APR::ThreadMutex to work so I offered to roll my own mutual exclusion code when, *bong*, I realized this would be trivial to do with a simple pipe. It is easiest to use as a very simple mutex (see Synopsis above). You can also u...
