A class providing an object based interface to SysV IPC semaphores....

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. ...

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...

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...

A simple interface to a resource value in a semaphore set....

"IPC::SysV" defines and conditionally exports all the constants defined in your system include files which are needed by the SysV IPC calls. Common ones include IPC_CREAT IPC_EXCL IPC_NOWAIT IPC_PRIVATE IPC_RMID IPC_SET IPC_STAT GETVAL SETVAL GETPID ...

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::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...
