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. ...

IPC::Semaphore::SmokeSignals - A mutex and an LRU from crack pipe technology

++

++

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...

Win32::IPC - Base class for Win32 synchronization objects

2 ++

2 ++

This module is loaded by the other Win32 synchronization modules. You shouldn't need to load it yourself. It supplies the wait functions to those modules. The synchronization modules are Win32::ChangeNotify, Win32::Event, Win32::Mutex, & Win32::Semap...

IPC::Shareable - Use shared memory backed variables across processes
