This is a package that can be used to share information between different processes using several types of shared memory containers.

A few shared memory container classes are provided implementing the same interface: file based, SysV shm, MySQL record.

The interface has functions for atomically fetching or storing shared memory data and also functions to start or finish transactions that allow multiple read or write access operations to be safely execute assuring the necessary integrity.

 Using shared memory is a solution for exchanging information between two or more processes or programs, that may or may not be running at the same time, in the same computer or even in different computers.

The uses of shared memory can be for instance: accessing to information application variables, exchanging messages between programs, etc..

Depending on the requirements of the applications that can benefit from its use, shared memory can be implemented using for instance OS specific shared memory extensions, memory mapped files and database accessible remotely via a network.

This class implements an abstracted solution that provides a single interface for accessing storing and retrieving information from different types of shared memory containers, thus making it possible to switch between container types as the requirements of an application evolve.
